Photo-thermo sensitive genie male sterile indica rice(PGMR) with leaf color marker is more advantageous than those without marker in hybrid seed production by two-lines method when abnormal summer low temperature occurs. An indica PGMR rice, Zhongzi S with purple-leaf marker was developed by incorporating a recessive gene controlling purple leaf into a ther-moperiod sensitive genie male sterile (TGMR) indica rice W6154S by backcrossing.

Photo-thermo sensitive genie male sterile indica rice(PGMR) with leaf color marker is more advantageous than those without marker in hybrid seed production by two-lines method when abnormal summer low temperature occurs. An indica PGMR rice, Zhongzi S with purple-leaf marker was developed by incorporating a recessive gene controlling purple leaf into a ther-moperiod sensitive genie male sterile (TGMR) indica rice W6154S by backcrossing. It was shown that under natural condition of Hangzhou (30°05'N), Zhongzi S was completely male sterile for over 25 days in summer. Further study of Zhongzi S in phytotrons with 3 photoperiods (P)×3 temperture (T) treatmemts showed that under high temperature (30. 1 ℃ ) Zhongzi S had complete or high male sterility with all photoperiods (15. 0 h, 14. 0 h and 12. 5 h). Variance analysis of the seed setting of Zhongzi S indicated that its photoperiod (P) effect is not significant, but its temperature (T) and PXT effect is significant. F1 hybrids of Zhongzi S with 15 va- rieties of 3 types of indica, japonica and intermedicate showed that Zhongzi S has good combining ability.

带标记的光-温敏核不育系在制种后对其F_1能籍标记性状在苗期检出假杂种,减少在生产应用中的风险。本研究采用中国水稻研究所保存的一份带紫叶标记的籼型紫叶稻(CN-pl)和湖北省农科院粮作所育成的温敏核不育系W6154S杂交,在F_2代选择紫叶稻回交一次后,以系谱法逐代选择而育成了带紫叶标记的光-温敏核不育系-中紫S_0在杭州(30.050N)的自然条件下中紫S具有延续25天的不育期,在人工气候箱控制条件下,中紫S在30.1℃的高温下,不同的光照长度处理基本上表现完全不育,自交结实率的方差分析结果表明,中紫S的光长效应不显著,温度效应和光温互作效应分别达到显著和极显著水准,属光温互作型雄性核不育系,经用籼型、粳型及籼粳中间型三类合计15个品种(系)作父本与中紫S杂交,对杂种一代的杂种优势结果分析表明,中紫S具有较强的配合力。

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...

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。

Several types of leaf color mutants were obtained by using 60 Co γ gamma rays treatment on dry seeds of maintainer long te fu B. In M 2 generation, the mutation frequencies of albino, yellowing and striping mutation lines at seedling stage were 0.347%, 0.041% and 0.031%, respectively. Investigations on their growth dynamics revealed that the average leaves and tillers of the whole yellowing and striping mutation lines were different from the original parent, but some mutants could recover to...

Several types of leaf color mutants were obtained by using 60 Co γ gamma rays treatment on dry seeds of maintainer long te fu B. In M 2 generation, the mutation frequencies of albino, yellowing and striping mutation lines at seedling stage were 0.347%, 0.041% and 0.031%, respectively. Investigations on their growth dynamics revealed that the average leaves and tillers of the whole yellowing and striping mutation lines were different from the original parent, but some mutants could recover to normal green at three leaf stage, and their leaves and tillers were similar to that of the control. In M 4BC 1 populations, there were two types of leaf phenotype segregation: normal green plants and the plants with leaf color marker, and their segregation were all about 1∶1. According to the characteristics of leaf color expression at seedling stage and later growth stage, these mutant lines in M 4 generation were classified into 6 types. Observations on the plant height, No. of panicles per plant, No. of total grains per panicle, seeds set per panicle and pollen fertility of M 4 mutant lines and plant height and No. of panicles of corresponding M 4BC 1 plants were conducted, the results showed that the agrinomical traits of those lines, which could recover to normal green, and corresponding M 4BC 1 plants with leaf color marker were similar to that of the corresponding control.

用60Co-γ射线直接辐照龙特甫B干种子,诱发获得了多种类型叶色突变体。M2 代按苗计,白化、黄化和条纹三种叶色突变体的频率依次为0.347% ,0.041% 和0.031% 。对M2 代黄化和条纹两类突变群体的生长发育动态研究发现,其平均叶片数和分蘖数与对照有较大的差异。但有一些黄化和条纹突变体在三叶期后即可转为绿色,其叶片数和分蘖数与对照相近。在用这些叶色突变体与龙特甫A 杂交、回交后的M 4BC1 群体中,分离出正常绿色和带有叶色标记的两类不育株,二者之比接近1∶1。根据苗期和成株期的叶色特征,这些突变系分为 6 种类型。对M 4 突变系的株高、单株穗数、每穗总粒数、每穗实粒数和结实率及相应的 M4BC1 植株的株高和单株穗数进行了考察,发现转绿型突变系及其相应的M4BC1 带叶色标记植株的农艺性状与相应的对照相仿。
