     The results showed that the leaf color and flower color were controlled by one pair of qualitative gene which was expressed incompletely dominant. Linkage analysis showed that the leaf color trait and the intraday flower color traits were linked completely,while the leaf color trait and the brown fiber trait were not linked,so two traits were independent inheritance. Allele test indicated that the mutant gene loci were different from the classic red plant gene loci(R1).

8 strains of leaf color mutants induced by 60Co-γ irradiation from Thermo-sensitive genie male sterile line 2177s, were obtained. According to differences in their response to temperature , these lines were classified into three types (Table 1), namely those whose mutated leaf color traits expressed under high temperatures, under low temperatures and under all temperatures tested.

8 strains of leaf color mutants induced by 60Co-γ irradiation from Thermo-sensitive genie male sterile line 2177s, were obtained. According to differences in their response to temperature , these lines were classified into three types (Table 1), namely those whose mutated leaf color traits expressed under high temperatures, under low temperatures and under all temperatures tested. Genetic analysis of three temperature-insensitive lines indicated that all of the mutated traits were controlled by a single recessive gene (Table 2). Except LCM6, the agronomic traits of the other two lines were similar to or better than those of 2177s. Meanwhile investigation on combining ability and spikelet fertility showed that many lines maintained the TGMS characteristics and combining ability like 2177s. When mixed with the seeds of hybrid rice "Shanyou 63", the seedlings with leaf color marker could be distinguished easily, and the seed Ling competing ability was significantly lower than that of the hybrid rice "Shanyou 63".

~(60)Co-Υ射线诱发的8个籼型温敏核不育系水稻叶色突变系可分为三种类型,即叶色突变高温表达型、低温表达型及温钝型。对温钝型3个突变系研究发现,该性状由单一隐性基因控制,其农艺性状除LCM6外与对照2177s相似或有所改观,育性转换特性和配合力也与对照相仿,对杂种优势无细胞质负效应。与杂交种“汕优63”混合播种时,叶色标记性状表达明显,幼苗竞争能力明显弱。

A novel type of photo-thermo sensitive genic male sterile (PTGMS) rice line Yut u S labeled with green-revertible albino leaf color marker was developed from t he 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 64 S , however the major agronomic characters, fertility characteristics, combining a bility, disease resistance, and grain...

A novel type of photo-thermo sensitive genic male sterile (PTGMS) rice line Yut u S labeled with green-revertible albino leaf color marker was developed from t he 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 64 S , however the major agronomic characters, fertility characteristics, combining a bility, disease resistance, and grain quality of Yutu S were similar to those o f Pei′ai 64S in mature plant. Physiological compensation mechanism analysis sh owed 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 prospects of utilization of Yutu S in the two-line hybrid rice production were discussed.

A new mutant in upland cotton was reported and named the sub-red plant by Chen Xu-sheng in 2004.The results of observations on the sub-red plant showed that there were obvious differences among the sub-red plants,the classic red plants and the normal green plants at every stage.As concerned cotyledon and neonatal color,the classic red plant's was sanguine,the normal green plant's was green while the sub-red mutant's was slightly red.During the flowering stage there was visible distinctness among the three...

A new mutant in upland cotton was reported and named the sub-red plant by Chen Xu-sheng in 2004.The results of observations on the sub-red plant showed that there were obvious differences among the sub-red plants,the classic red plants and the normal green plants at every stage.As concerned cotyledon and neonatal color,the classic red plant's was sanguine,the normal green plant's was green while the sub-red mutant's was slightly red.During the flowering stage there was visible distinctness among the three genotypes as following:(1) The color of the intraday flower was different,the normal green plant's was white,but the sub-red mutant plant's was ponceau,which surpassed the classic red plant's;(2) The leaf color of classic red plant was red,the normal green plant's was green while the sub-red mutant's was slightly red and its leaf color gradated near green as the leaves grew up gradually.The inheritance of the sub-red mutant including the leaf color traits and the intraday flower color was studied.The results showed that the leaf color and flower color were controlled by one pair of qualitative gene which was expressed incompletely dominant.Linkage analysis showed that the leaf color trait and the intraday flower color traits were linked completely,while the leaf color trait and the brown fiber trait were not linked,so two traits were independent inheritance.Allele test indicated that the mutant gene loci were different from the classic red plant gene loci(R1).According to above results,it was clear that the sub-red plant was a new quality trait mutant in upland cotton,which gene was named Rs tentatively.There are obvious phenotype difference between the sub-red plant mutant and the normal green plant in seedling and flowering stages.Remarkably,F_1,which come from the cross the sub-red mutant and the normal green plant,has good photosynthesis function.Therefore,we can use the new mutant trait as an early mark character,and at the same time make use of its F_1 hybrid to improve photosynthesis efficiency and to further increase yield.In a word,the mutant will be applied broadly in breeding.

分析了陆地棉亚红株突变体的淡红叶性状与当日红花性状的质量遗传规律,结果显示,淡红叶性状是受一对不完全显性基因控制的质量性状。连锁分析表明:淡红叶性状与当日红花性状完全连锁,是受同一对显性基因控制的质量性状;淡红叶与棕絮性状符合两对性状完全独立分离规律,不存在连锁遗传关系。等位性测定显示,淡红叶性状与经典红叶性状杂交后代,符合两对显性基因控制的独立分离理论比例,表明控制亚红株突变的基因与控制经典红叶的R1基因不在同一基因位点。根据以上试验结果,推定陆地棉亚红株突变是一个新的质量突变性状,暂将它的基因符号定为RS。
