摘要： 玉米花粉植株的育成,为单倍体育种提供了可能。但移栽成活率低,结实株数少,影响了在育种实践中的应用。我们研究了花粉植株的生理特性,并通过调节激素,改善相应的栽培管理措施,创造最适的生育条件培育壮苗,结果移栽成活率大幅度提高。在生育期间保持18～32℃,增加光照时间和强度,结实株数有了明显的增加。

Abstract: The achievement on the development of plants derived from maizehybrids provides possibility for utilizing haploids in maize breeding.Atpresent it can hardly be applied in reeding because of the difficulty inobtaining enough number of vigorous fertile plants after transplanting.Ina preliminary study
