Ⅱ.向日葵遺傳質雄不稔性之研究

謝桑煙 張明正

摘  要

以自加拿大引進之遺傳質雄不稔性材料為母本與育成自交系S536等4系統雜交,在其F2後裔1,163株中,MF佔880株,MS為283株,適成3與1之比,顯示遺傳質雄不稔性一對穩性因子所控制。


Studies on Male-sterility of Sunflower (Helianthus annuus L.) I. Study on Genetic Male-sterility of Sunflower

S. Y. Hsieh and M. C. Chang

Summary

       The crossing between a genetic male-sterile came from Canada used as female and S5 36 etc. four inbred lines that used as male obtained 1163 F2 plants.  Among these offspring, 880 plants were male-fertile and 283 plants were male-sterile. Their segregation ratios of male-fertile to sterile were 3:1.

       The result suggested that g.m.s. is caused by a single recessive gene.
