以谷10A和谷11A作为不育材料,以来自不同生态区的谷子品种作为恢复材料,采用不完全双列杂交方法分析了这两个新谷子不育系和不同生态区恢复系的配合力和遗传力,为选育不育系和选配强优组合提供依据.结果表明:①不育系谷10A的一般配合力较高,恢复系中一般配合力较高的有K1011、日朝谷、晋谷21、冀谷26、大同28、冀谷24.谷10A与锦谷14、大同28组合的特殊配合力较高;不育系谷11A的一般配合力虽然不高,但是其与日朝谷、冀谷26、K1011组合的特殊配合力较高.②遗传力分析表明:株高、产量、千粒重、穗长这些性状的遗传力在F1群体中较高,受环境影响较小,对这些性状进行选择是有效的;单穗重、穗直径、穗粒重、千粒重、产量的狭义遗传力较低,说明显性效应和上位性效应在F 1群体中对这些性状有很大影响;而株高和穗长这两个性状在F 1群体中主要是基因累加效应贡献大.
以穀10A和穀11A作為不育材料,以來自不同生態區的穀子品種作為恢複材料,採用不完全雙列雜交方法分析瞭這兩箇新穀子不育繫和不同生態區恢複繫的配閤力和遺傳力,為選育不育繫和選配彊優組閤提供依據.結果錶明:①不育繫穀10A的一般配閤力較高,恢複繫中一般配閤力較高的有K1011、日朝穀、晉穀21、冀穀26、大同28、冀穀24.穀10A與錦穀14、大同28組閤的特殊配閤力較高;不育繫穀11A的一般配閤力雖然不高,但是其與日朝穀、冀穀26、K1011組閤的特殊配閤力較高.②遺傳力分析錶明:株高、產量、韆粒重、穗長這些性狀的遺傳力在F1群體中較高,受環境影響較小,對這些性狀進行選擇是有效的;單穗重、穗直徑、穗粒重、韆粒重、產量的狹義遺傳力較低,說明顯性效應和上位性效應在F 1群體中對這些性狀有很大影響;而株高和穗長這兩箇性狀在F 1群體中主要是基因纍加效應貢獻大.

@@@@Taking Gu10A and Gu11A as sterile materials and millet varieties from different ecotope as recovery materials,this study analyzed the combining ability and heritability of these 2 novel foxtail millet sterile lines and different ecotope restorers by incomplete diallel cross method,so as to provide basis for sterile line breeding and selecting optimal combination. The results show that ① Sterile Gu10As general combining ability is higher,and restorers with higher general combining ability are K1011,Richaogu,JinGu 21,JiGu 26,Datong 28 and Jigu 24. The special combining abilities of Gu10A with Jingu 14 and Datong 28 combinations are higher;although sterile Gu11As general combining ability is low,its special combining abilities with Richaogu or Jigu 26 and K1011 combinations are higher than others. ② The heritability analysis indicates that the heritabilities of plant height,yield, thousand kernel weight,and spike length in F 1 group are larger,because the environment impact is small. The selection for these traits is effective. The narrow-sense heritabilities of spike weight,spike diameter,spike grain weight,thousand kernel weight and yield are lower,indicating that the dominant and epistatic effects in F 1 group greatly influence these characteristics;and plant height and spike length of these 2 traits in F 1 group are mainly caused by gene additive effect.
