| 摘 要： | 采用5(不育系)×3(恢复系)的 NCⅡ设计,对杂种小麦产量、产量构成因素以及蛋白质含量的生理特点进行了研究,结果表明:成熟期植株总氮同化量和生物产量与蛋白质产量和单株产量相关显著,而与蛋白质含量无显著相关,收获指数与产量呈正相关,与蛋白质含量呈显著负相关;氮收获指数与产量正相关而与蛋白质含量无关,穗粒数对穗粒重的作用明显大于千粒重。克穗粒数、穗草比对穗粒数的作用大于花前同化物量;其中粒重的大小主要由灌浆速度所决定,与灌浆持续期关系不大;粒重优势主要是由于 F_1籽粒灌浆速度的提高所造成。

| Abstract: | The heterosis of grain yieid and protein yield is usually postive while that of the grain pro- tein content negative.The heterosis of grain yield was influenced by heterosis of biological yield and HI; The heterosis of HI was lower than that of biological yield.The value of Vgca was greater than of Vsca in all of the 8 quantitative traits.There were great differences among those traits on the Vgca% accounted of the genetic variance.NHI and grain number per spike dry weight and leaf area duration are mainly ... |
