【摘要】 选择有代表性的5个光敏、广亲和水稻品种和4个旱稻品种按照p×q不完全双列杂交配制杂交组合,并对其F1代的株高、穗长、单株结实率等9个主要农艺性状进行了配合力分析,考查了亲本的Gca效应和杂交组合的Sca效应值。结果表明:在一般配合力方面,95076 S和农垦58 S是较好的母本品种,S 13和热大1号是较好的父本品种;在特殊配合力方面,7001 S×热大1号和农垦58 S×热大7号在各性状上都有较好的效应。更多还原

【Abstract】 Five photosensitive,widely compatible paddy rice varieties and 4 upland varieties were crossed in a p×q partial diallel cross experiment,the combining ability of 9 main agronomic traits of the F₁s were analyzed,and the general combining ability effect of the parent varieties and the specific combining ability effect of the cross combinations were calculated.As far as general combining ability is concerned,95076 S and Nongken 58 S were desirable female parents and S 13 and RD 1 were good male parents.For specific combining ability,the cross combinations of 7001 S×RD 1 and Nongken 58 S×RD 7 showed good effects.更多还原
