| Abstract | 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. |
| Abstract Alternative | 抵抗性と罹病性の両親間の交雑に由来する2組のF2集団とその後代のF3系統を用いて、大麦網斑病における抵抗性の選抜効果を推定した。F3系統の平均値と分散から、病斑指数の分散が小さく、すでに固定した系統が多数存在したので、抵抗性は少数の遺伝子に支配されているとみられた。F2個体とF3系統間の親子相関、親子回帰およびF2の選抜差とF3系統の遺伝獲得量から遺伝率を推定したところ、2組の交雑組合せで抵抗性親の病斑指数は異なっていたにもかかわらず、3種類の遺伝率の推定値はいずれも0.6～0.8の値を示した。遺伝率が高く、しかも関与する遺伝子数であるため、雑種集団で連続変異を示す場合の大麦網斑病抵抗性の選抜はF2からでも効果的とみられた。 |

| Abstract | 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. |

| Abstract | A total of 162 strains of wild barley, Hordeum spontaneum C. Koch originating from Iran, Iraq, Turkey and Central Asia, were tested for resistance to powdery mildew. Then, the variation of resistance was compared with that of 145 local varieties of cultivated barley (Hordeum vulgare L.) originating from the same region of the wild barley collection. Ten different isolates of the parasite with Japanese origin were separately inoculated onto the first leaves of the host plants. The infection types were classified into the following: i, immunelike; R, highly resistant; M, moderately resistant; and S, highly susceptible. Resistant strains with i, R or M infection type were more frequent among wild barleys as compared with the cultivated forms. It is noteworthy that among these three resistant reactions,the M type was most frequent in the wild barley. To compare the degree of resistance to a total of 10 isolates, the resistance score was calculated in each of the wild and cultivated strains as the following: Scores 1,2,3 and 4 were given to the infection types of i, R, M and S, respectively, and the mean score for 10 isolates was calculated. Wild barley showed significantly low resistance scores as compared with those of cultivated barley. This was also confirmed by the cluster analysis; the cluster with more resistance to 10 isolates consisted of many strains of wild barley. Next, the resistance of wild barley was characterized by their broader effective ranges to different isolates. According to the x2 test for independence of reactions to two different isolates, the resistant factor(s) involved in wild barley was confirmed to be rather non-specific to the parasite. It was concluded that H. spontaneum may be useful genetic resources for the breeding of resistance to powdery mildew as well as local varieties. |
| Abstract Alternative | 病原菌の変異による抵抗性品種の罹病化は耐病性育種の大きな問題である。永続性のある抵抗性品種を育成するための遺伝資源を得る目的で、病原菌と長期間共進化してきた野生オオムギ（Hordeum spontaneum）と在来種のうどんこ病抵抗性を評価した。材料はH.spontaneum162系統ならびにこれらと産地を同じくする在来品種145系統である。接種には日本のうどんこ病菌H1,h4,h9の他に人為的交雑によって育成した7菌株を加えた10菌株を用いた。第1葉の反応を免疫的抵抗性（i）、高度抵抗性（R）、中度抵抗性（M）および罹病性（S）に分類した。その結果、以下のことが明らかとなった。1）抵抗性（i,R,M）を示す系統の頻度は大部分の菌株において野生種の方が高かった。2）野生種の抵抗性は在来種よりも多数の菌株に対して有効であった。3）クラスター分析の結果、野生種の大部分が同一のグループに属し、在来品種は多くのサブグループに属することが明らかにされた。4）これらの事実から、オオムギの野生種はうどんこ病抵抗性育種の遺伝資源として在来種と同等あるいはそれ以上に有用であるとみられた。 |

| Abstract | 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. |
| Abstract Alternative | 日本ならびにカナダで採取した大麦網斑病菌4菌株を、岡山大学資源生物科学研究所大麦系統保存施設の保有する2,200あまりの品種に接種して、各菌株に対する抵抗性遺伝子源を評価すると共に病原性の分化を検討した。結果の概要は以下の通りである。1）3回にわたって44品種に4菌株を接種した予備試験の結果、病斑指数の品種変異は極めて大きく、品種の抵抗性に対する接種時期の影響は小さかった。2）供試4菌株に対するオオムギ品種の抵抗性の頻度分布はいずれも連続的で、そのピークは抵抗性側であった。各菌株間の病斑指数は有意な正の相関関係にあり、菌株間の病原性の分化は小さかった。3）各菌株に対する抵抗性遺伝資源はエチオピア、北アフリカおよび朝鮮半島に多かった。一方、日本で採取した2菌株に対する罹病性の品種はトルコおよびヨーロッパに多いのに対して、カナダで採取した菌株に対する罹病性の品種はネパールに多かった。また、ネパールに由来する品種の病斑指数は、日本の2菌株に対しては抵抗性と罹病性の2群に分かれたが、カナダの2菌株に対しては連続的な分布を示した。特に、カナダの菌株WRS102に対するネパール由来の品種の反応は、強度の抵抗性を示す品種がなく、ピークが罹病性側に片寄っており、日本の菌株に対する反応とは大きく異なった。4）日本で採取したK105とカナダで採取したWRS102の病斑指数の菌株間相関係数は、4菌株の組合せの中で最も小さく、K105とWRS102の病原性は多少分化していた。なお、K105に抵抗性でWRS102に罹病性の品種は25品種であり、そのうち20品種がネパール由来で、かつ、そのほとんどが小穂脱落性東亜型を示した。従ってK105に抵抗性でWRS102に罹病性の遺伝子は、ネパールの東亜型品種に偏在しているとみられる。 |
