三种光温敏核不育水稻种质的遗传研究

STUDIES ON THE INHERITANCE OF THREE TYPES GERMPLASM IN PHOTO-THERMO SENSITIVE GENIC MALE STERILE RICE

摘要: 农垦５８５、Ｗ６１５４Ｓ、Ｗ７４１５Ｓ的光温敏不育性由核内两对隐性基因控制，而安农Ｓ－１光温敏不育性由核内一对隐性基因控制；农垦５８Ｓ与Ｗ６１５４Ｓ、Ｗ７４１５Ｓ、５４６０Ｓ之间，Ｗ６１５４Ｓ与安农Ｓ－１、５４６０Ｓ之间光温敏不育基因部分等位，农垦５８Ｓ与安农Ｓ－１之间，Ｗ６１５４Ｓ与Ｗ７４１５Ｓ之间，Ｗ７４１５Ｓ与安农Ｓ－１、５４６０Ｓ之间以及安农Ｓ－１与５４６０Ｓ之间的光温敏不育基因完全不等位

Abstract: Sterility of PTGMRS deriving from Nongken 58S germplasm and 5460S germplasm was governed by two pairs of recessive genes, but that of Annong S-1 governed by a couple of recessive major genes. An allelism test involving five PTGMRS revealed that Nongken 58S and W6154S, Nongken 58S and W7415S, Nongken 58S and 5460S, W6154S and Annong S-1, W6154S and 5460S possessed partially identical photo-thermo sensitive sterile genes; Nongken 58S and Annong S-1, W6154S and W7415S, W7415S and Annong S-1, W7415S and 5460S, Annong S-1 and 5460S had different photo-thermo sensitive sterile genes.
