摘要： 以我国主栽的籼型光温敏核不育系培矮64S为起始材料，利用300 Gy的60Co-γ射线辐照干种子，经多代选择选育了一个携带白化转绿型叶色标记的新型不育系玉兔S。该不育系苗期性状明显比原亲本培矮64S差，但成熟期的主要农艺性状、育性特征、配合力、抗病性及稻米品质均与培矮64S相仿。补偿性生理机制研究表明，在分蘖、拔节和开花阶段玉兔S叶绿体内腺苷酸激酶和RuBP羧化酶的活性要比培矮64S高。遗传研究表明，白化转绿型突变性状受单隐性基因控制，并在幼苗阶段特异性表达。对不育系玉兔S在两系杂交水稻生产中的应用前景作了讨论。

Abstract: A novel type of photo-thermo sensitive genic male sterile (PTGMS) rice line Yutu S labeled with green-revertible albino leaf color marker was developed from the leading PTGMS indica rice line Pei′ai 64S with 300 Gy 60Co gamma rays irradiation of the dry seeds through continuous selections. The seedling charac ters of Yutu S were significantly worse than that of the wild type Pei′ai 64S , however the major agronomic characters, fertility characteristics, combining ability, disease resistance, and grain quality of Yutu S were similar to those of Pei′ai 64S in mature plant. Physiological compensation mechanism analysis showed that an increase in the activity of adenylate kinase and ribulose-1,5-bi sphosphate carboxylase was observed in the chloroplast of Yutu S during tiller ing, booting, and flowering stages. Genetic study indicated that the mutated gre en-revertible albino leaf color trait specially expressed at seedling stage wa s controlled by a single recessive gene. The prospe...更多cts of utilization of Yutu S in the two-line hybrid rice production were discussed.
