| 摘 要： | 利用小麦三雌蕊突变体与绵阳29杂交,再以绵阳29为轮回亲本,多次回交,并结合人工选择,构建了小麦三雌蕊性状的近等基因系.对小麦三雌蕊突变体,绵阳29以及小麦三雌蕊性状近等基因系的小穗数﹑穗长﹑穗粒数﹑叶长﹑叶宽﹑茎粗﹑千粒重和单株粒重等8个农艺性状进行了分析,结果表明:其中除小穗数和穗长没有显著性差异,其余6个农艺性状均表现出显著性差异.近等基因系在穗粒数、叶长、叶宽、茎粗和单株粒重这5个农艺性状明显高于轮回亲本,而千粒重明显低于轮回亲本.由此可见Pis1基因有增加穗粒数、叶长、叶宽、茎粗和单株粒重的效应,有降低千粒重的副效益.

| Abstract: | The near-isogenic lines of three pistils in wheat were derived from Triticum.aestivum TP mutant/T.aestivum cv.Mianyang 29 by conventional breeding.The main agronomic traits of near-isogenic lines of three pistils and their parents T.aestivum TP mutant,T.aestivum cv.Mianyang 29 were studied,including spikelet number,spike length,grain number per spike,leaf length,leaf width,stem diameter,1000-kernel weight,and grain weight per plant.The results indicated that the agronomic traits had significant differences ... |
