摘要
对通过辐射诱变获得的具有白化转绿特性的水稻光温敏核不育突变体的遗传及其生物学特性进行了研究。结果表明,这些突变体可分为3种类型:白化转绿类型(W2、W3、W4和W10),白化转黄绿类型(W9)和白化转绿后期转白复绿类型(W1和W7)。这些突变体的白转绿特性都是受一对隐性基因控制,具有与原不育系"培矮64S"相似的农艺性状和育性转换特性,它们的杂种具有与原杂交稻相似的株叶形态、分蘖和株高生长动态,但是它们的产量构成因素依不同的突变系而表现不同,其中W1、W2和W3的杂种有与原杂交稻相似的产量潜力,具有较好的育种应用价值。
Inheritance and main agronomic traits of photo-thermo-sensitive genic male sterile line with green-revertible albino leaf were investigated. The results indicated that the mutants might be divided into three types：albino regreening type（ W2, W3, W4 and W10）, albino to kelly type（W9） and abino-regreening-albino-regreening type（W1 and W7）. Genetic study indicated that green-revertible albino leaf color trait of the mutants as controlled by a single recessive gene. These mutants had similar agronomic traits and fertility characteristics to the corresponding male sterile line ＂Peiai 64S＂. The hybrids of these mutants had similar characteristics with original-hybrids in plant type, developing of tillers and plant height. The yield components of the mutant hybrids were different depending on different mutants. The yield potential of hybrids of W1, W2 and W3 were similar to the original-hybrid. The results also indicated that W1, W2 and W3 had breeding application value.
