各类作物高蛋白含量和与其有关的数量性状改良的选择,面临的一个问题是随着籽粒蛋白质含量的增加,亲本的高产水平下降。这主要是由于产量和籽粒蛋白质含量,籽粒饱满度和蛋白质含量间存在负相关(JOHNSON 等1971;SHAHANI 1980.)。蛋白质含量的复杂遗传(COWL EY and Wells 1980;KERTESZ 等 1980;SHAHA-N1 等1983),环境因子对籽粒蛋白质含量的影响(BABYAKIN and PISCUNOVA1979:SHAHANI 等1983),施肥对籽粒蛋白质含量的效应(COCHRAN 等1978
One of the problems faced by the high protein content of various crops and their associated quantitative trait selection is that the high yield of the parent decreases as the protein content of the grain increases. This is mainly due to the negative correlation between yield and grain protein content, grain plumpness and protein content (JOHNSON et al. 1971; SHAHANI 1980.). The complex inheritance of protein content (COWL EY and Wells 1980; KERTESZ et al 1980; SHAHA-N1 et al 1983), the effect of environmental factors on grain protein content (BABYAKIN and PISCUNOVA 1979: SHAHANI et al 1983), the effect of fertilization on grain protein content Etc
