| 抄録 | Hull-cracked grain which causes low germinability and low malt extract has been observed in malting barley varieties mainly in the western part of Japan. In the first part of this study, more than 600 two-rowed barley varieties were examined for the percentage of hull-cracked grains. A markedly skewed frequency distribution pattern was observed for varietal variation of hull-cracked grain percentage. More than 80% of the varieties developed less than 5% hull-cracked grains, while a few of the varieties frequently developed the hull-cracked grains. The maximum hull-cracked grain percentage was as high as 61% in Yoshikei 16. Improved varieties developed hull-cracked grains more frequently than the local varieties, indicating varietal improvement indirectly caused the hull-cracked grains. In the second part, nine two-rowed varieties were grown in eight different conditions to analyze the mechanism of hull-cracking. Variances due to varieties, environment and their interaction were all statistically significant. Some of the varieties developed almost no hull-cracked grains throughout the environmental conditions examined, while others sharply responded to the environmental conditions. The environmental correlation coefficient between 1,000-kernel weight and hull-cracked grains was as high as 0.918, indicating that hull-cracked grains had developed under favorable ripening conditions. |

| 抄録 | The influences of air temperature, precipitation, number of rainy days and sunshine duration on the crop situation index of wheat, six-rowed barley and two-rowed barley in Okayama prefecture were analyzed by using the data for the 30-year-period of 1966-1995. The crop situation index of these three crops showed high negative correlation with the precipitation in April and a positive correlation with sunshine duration in April. Precipitation over 150 mm or lesser sunshine duration under 190 hrs in April seems to reduce the yield of wheat and barley in Okayama. |

| 抄録 | Micrometeorological observations including turbulent fluxes and canopy surface temperatures were made in paddy in the summer of 1997. The sensible and latent heat fluxes were estimated by the gradient method under the assumption of similarity between the turbulent exchange coefficient for momentum and that for heat and water vapor. The surface temperatures measured by a thermal imager and water vapor pressures estimated from surface temperatures and relative humidity were used for temperature and water vapor at the height(d+z0) of U=0, where d is the displacement height, z0 the roughness length and U the mean wind velocity. The sensible and latent heat fluxes estimated by the gradient method depicted typical diurnal varietions. The turbulent fluxes by the present method and eddy correlation method showed fairly good agreement, especially for latent heat fluxes. These results confirmed that this method is a promising one. |

| 抄録 | The relationship between the indole alkaloid gramine concentration and aphid population was examined seedling and maturation stages in 14 barley lines of Hordeum spontaneum and H. unlgare. The density of Schizaphis graminum did not differ significantly with the gramine concentration in the seedling in the greenhouse. However, the population of Rhopalosiphum padi sometimes differed with the seedling. The plant resistance to the natural infestation of cereal aphids was obvious at the heading stage. There was a negative correlation between the high population density of aphids and gramine concentration. The gramine concentration was high in matured resistant resistant lines, especially wild lines, as compared with susceptible lines due to higher biodegradation activity. |

| 抄録 | To beer barley resistance to cereal aphids, the relationship between the aphid density and gramine concentration was examined in various barley lines including beer barley cultivars. All beer barley cultivars tested were resistant or moderately resistant to the aphids, especially Asahi 5 and Haruna Nijo were similar to a wild line, H603 (W603), for checking resistant. However, these beer barleys contained much less gramine than the wild barley line, suggesting that another resistant factor(s) affects cereal aphid density. |

| 抄録 | Selection effectiveness for the resistance to net blotch was estimated by using two sets of F2 and F3 populations derived from the crosses between resistant and susceptible parents. In every F2 and F3 population, disease ratings showed a continuous distribution. As many F3 lines with intermediate resistance had a smaller variance and homozygous genotype, the resistance might be controlled by a few genes. The heritabilities of the disease rating were estimated by correlation coefficients and regression coefficients between each F2 plant and the descended F3 lines. Another estimate for heritability was calculated by the selection differential in the F2 plants and genetic gain in the F3 lines. Despite the different level of resistance in the resistant parents of the two crosses, the three kinds of heritabilities estimated were similar and ranged from 0.6 to 0.8. Because of the fewer number of genes controlling the disease resistance and the higher heritabilities, selection in a early generation may be effective for net blotch resistance in barlcy. |

| 抄録 | Three species of Cyperaceous weeds, Cyperus iria (12 strains), C. microiria(12 strains) and C. amuricus (6 strains), were collected from different sites of Okayama, Tottori and Tokyo prefectures, and various morphological characters, biomass and seed production were observed on the plants which were cultivated at Kurashiki. The analysis of variance showed a significant difference among the strains in each character. However, the species overlapped with each other in most morphological characters. Prinipal component analysis on the 21 characters showed that 83% of the total variation could be explained by the first three components: the first component (37%) was regarded as factors concerning spikelet and seed production; the second component (28%) was regarded as factors concerned the size of vegetative parts; the third component (18%) was largely affected by seed weight and floret density. Scatter diagram on the first and third principal components showed that the 30 strains of three species divided into three groups, and strains in each group correspond to the three species without exception. Based on the second and third principal components, strains of C. microiria were further divided into three sub-groups according to size of vegetative parts. Using the cluster analysis, 30 strains of these species were divided into four large clusters; the first was composed of C. amuricus strains, the second was of three strains of C. microiria, the third included the remaining strains of C. microiria, and the last cluster was composed of C. iria strains. It may be concluded that C. microiria is composed of two or three ecotypes which are different in morphological and reproductive traits. |

| 抄録 | Net blotch caused by a fungus Pyrenophora teres Drechs. is a common disease in barley. Its source of resistance has been screened by many researchers by field evaluations or seedling tests inoculating a single isolatc. Since the pathogcnic variation of isolates has been reported in net blotch, resistance of the varieties to the disease may be different among the isolates with different pathogenicities. In this study, the pathogenic variation was examined and the varietal variation of the resistance was evaluated by inoculating with four P. teres isolates collected from Japan and Canada to more than 2,200 barley varieties of the world collection preserved at the Barley Germplasm Center of Okayama University. A preliminary inoculation test showed that the disease rating was affected little by the inoculation seasons. Disease ratings of varieties showed a continuous variation with a single mode in the resistant range in each of the four isolates. However, the correlation coefficient between Japanese isolate K105 and Canadian isolate WRS102 was as low as 0.55, indicating a slight pathogenic differentiation between these isolates. Significant correlation coefficients (r=.55~.78) among the ratings of isolates indicated that the pathogenicity to the varieties was rather similar and that the pathogenic differentiation was small among the four isolates tested. In general, varieties from Ethiopia, North Africa and Korea were more resistant than those from other regions. Varieties from Turkey and Europe were susceptible to Japanese isolates, while Nepalese varieties were susceptible to Canadian isolates. Twenty of 25 varieties which were resistant to the isolate K105 but susceptible to the isolate WR102 were from Nepal and most of those were Oriental-type (Bt bt2) in brittleness of rachis. These findings revealed an example of regional concentration of resistant gene in net blotch. |

| 抄録 | Half diallel F2 populations crossed among eight two-rowed barley varieties with warious percentages of hull ruptured grains were raised to analyze the inheritance of the trait. The percentage of grains with hull rupture varied from 0 to 87% among the parents. The diallel analysis revealed the following: the trait was predominantly controlled by the additive genes, and the dominance effect of some parents was also significant. However, the epistatic effect of the genes was not significant. The average dominance was 0.97. The heritability value was estimated as 0.57 and 0.91 in a narrow and a broad sense, respectivelly. The percentage of grains with hull rupture showed continuous and transgressive segregations in 28 F2 populations derived from half diallel crosses among eight parents. Heritability of the trait in a broad sense was 0.43~0.80(0.65 on average) in 28 F2 populations. |

| 抄録 | The callus forming ability and regenerating ability of the calli derived from mature and immature embryos of 132 barley varieties were examined. These materials were taken from a world-wide collection preserved at the Barley Germplasm Center of Okayama University. The callus forming ability varied widely according to genotype in both mature and immature embryos, but the varieties collected from Ethiopia showed low callus forming ability. Calli derived from mature embryos generally did not regenerate shoots, except for three Japanese varieties. The frequency of shoot regeneration from the calli derived from immature embryos was somewhat higher than that from those derived from mature embryos. Many of the Korean and Japanese varieties had a high shoot regenerating ability. However, few of the varieties from Ethiopia and Southwest Asia had a high shoot regenerating ability. No correlation was observed btween root regenerating ability and shoot regenerating ability of the varieties. No correlation was observed between callus proliferation and root regenerating ability between calli derived from mature and immature embryos. We could not find any difference in the shoot regenerating ability btween the two-rowed and six-rowed genotypes. |

| 抄録 | Twenty-two isolates of Pyrenophora teres Drechs. collected from Japanese and Canadian spring barleys were inoculated to 38 barley varieties having various genetic backgrounds. The analysis of variance for the discase ratings showed that there were significant differences both in the virulence of isolates and the resistance of varieties. However, the interaction among isolates and varieties was not statistically significant. Both Finlay-Wilkinson regression analysis and principal component analysis by Additive Main effects and Multiplicative Interaction effects(AMMI)model classified the isolates into three groups,which were different in origins and sympton types. A spot tyte isolate was distinguished from net type isolates by its generally high virulence. A slight pathogenic differentiation was suggested between Japanese and Canadian net type isolates. |
