摘要: 玉米生理成熟后,籽粒快速脱水,对于玉米品种充分利用有利的生长季节,提高籽粒产量和籽粒商用品质,提高种子质量都是很有现实意义的。生理成熟后,籽粒脱水速率品种间有很大差异,遗传上受加性效应基因支配,脱水速率与环境、品种形态特征及农艺特性有关;在广泛的玉米育种群体中,通过在田间对某些相关性状进行直接或间接选择,培育出高产、快速脱水的玉米品种是可能的。

Abstract: Grain moisture quick-loss is more significance for the maize variety utilizing fully favourable growth season, increasing yield of grain and its commodity quality, and improving the quality of seed, after physiological maturity in maize, The grain moisture loss rate of maize is greater in difference amony varieties. The difference is controlled by the additive inheritance effect, and it is highly inheritance for the grain moisture loss rate. The rate of grain moisture reduction relates to the environment, the morphological character and the agronomic traits. It is possible to breed the maize variety of high yield and grain moisture quick-loss by directly and indirectly selecting some relative traits in the field, and in the wide maize breeding population.
