本文旨在分析江淮下游酶白菜代表品种的杂种优势与配合力。产量、抗病性的杂种优势因组合、正反交而异。有些组合的表现还因年份、地点等环境条件而不同。评选出优势强而稳的高×瓢、瓢×花、花×高组合可供生产应用。亲本间在一般配合力、特殊配合力以及它们的波动程度上都有各自的特点,选配组合时对一般配合力、特殊配合力以及正反交效应都需注意。产量杂种优势利用的广义遗传力估计值为76.7—81.7％。
The purpose of this paper is to analyze the heterosis and combining ability of representative cabbage representatives in the lower reaches of Jianghuai. Heterosis of yield and disease resistance varies depending on the combination, back and forth. Some combinations of the performance also due to the year, location and other environmental conditions and different. Selected strong and stable high strength × scoop, scoop × flowers, flowers × high portfolio for production and application. The parents have their own characteristics in the general combining ability, the special combining ability and the degree of fluctuation of their parents. All the combinations should pay attention to the general combining ability, special combining ability and the positive and negative cross effects. The estimated generalized heritability of yield heterosis is 76.7-81.7%.
