摘  要：
早熟马铃薯品种熟期短,经济效益高,已经成为农民增收致富的重要作物之一。为了解马铃薯熟性的遗传规律,为早熟品种选育的亲本选配提供依据,以早熟品种中薯3号为亲本分别与早熟、中早熟和晚熟亲本品种杂交形成的6个杂交组合后代为材料,对不同类型的杂交组合后代的熟性和产量相关性状进行了分析,结果表明:熟性是由多基因控制的、存在细胞质效应的数量性状;配制早熟×晚熟组合既能保证杂交后代中有较高比例的早熟和中早熟材料,也能保证杂交后代中有较高比例的高产材料;中薯3号是一个优良的、配制早熟杂交组合的育种材料。

摘  要：
Early-maturity potato,with short growth period and high economic benefit,already become one of main crops to increase farmers income. In order to understand genetic character of potato maturity and provide a basis for parental combination of breeding crosses,we analysed the maturity distribution and its correlation with traits related to yield using progenies from six crosses that early-maturity cultivar Zhongshu 3 hybridizes with early-maturity,mid-maturity and late-maturity cultivar,respectively. The results showed that,potato maturity was controled by multi-genes and inherits as quantitative trait and nucleo-cytoplasmic interaction. It was feasible to make crosses between early-maturity female parent and late-maturity parent for selecting progeny with both early-maturity and high yield. It is a good parental material for Zhongshu 3 to make breeding crosses for early-maturity.
