摘要 T 型杂种小麦单株产量和蛋白质产量表现正向杂种优势,蛋白质含量表现无优势。产量优势表现与生物产量优势和收获指数优势有关,生物产量优势高于收获指数优势。所研究性状一般配合力方差均大于特殊配合力方差,但其在遗传总方差中的相对重要性因性状而异,克穗粒数、氮收获指数和叶面积持续期主要受基因加性效应影响,净同化率、比叶重、穗草比、谷叶比和收获指数既受加性效应又受非加性效应的影响。 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 con- trolled by gene additive effect,Specific leaf weight and Mean Net Assimilation Rate and Grain-leaf area and Spike-Vegetative organ dry weight ratio were controlled by genes of additive effect and noadditive ef- fect.
