Abstract
Using 10,473 barley accessoins and 16,480 gamma-ray lines, root fluorescence mutants which have been reported in order crops, such as soybean, were screened. No spontaneous mutant was found,but an artificial mutant whose root tips emitted a pink glow under ultraviolet light was obtained by the gamma-ray irradiation. The mutant was controlled by a recessive gene named frp 'fluorescent reaction-pink'. It was poor growth and was lethal. The transmissoin rate of the mutant gene was about 80% of that of the normal allele. Thus the segregation in the heterozygous populations was ca. 4 normal to 1 mutant. The frp gene is located close to gl-3, 'glossy leaf-3' on the 4H chromosome.

オオムギ10,473品種およびコムギ1,140品種を供試して根の蛍光変異体を検索したが、変異体を見出すことはできなかった。オオムギ品種ふじ二条にガンマー線を3世代にわたって90KR照射したM8世代16,480系統の中から根端が紫外線によってピンクに発色する変異体が3系統得られた。これらは同一の突然変異に由来する姉妹系統の可能性が高い。この蛍光変異体は劣性1遺伝子frp(fluorecent reaction pink)に支配される。frpは4H染色体のgl-3近傍に座乗し、その伝達率は正常型の対立遺伝子に比べて0.8程度と低い、frpは致死遺伝子であるがヘテロ維持が可能である。
