摘要
以8个高代自交系为试材,按不完全双列杂交法配制16个组合,并进行了配合力分析。供试8个亲本中,有1个亲本平均单瓜重、瓜把长度具有较大的正向效应值;有1个亲本瓜粗、心室直径具有较大的负向效应值。在所配的16个组合中,有3个组合的平均单瓜重表现出较大的正向效应值,有3个组合的瓜把长度表现出较大的负向效应值。瓜条粗度和心室大小的特殊配合力在组合间表现出较大差异,瓜把长和平均单瓜重的狭义遗传力较低,而瓜条长度、瓜粗和心室直径的遗传力较高,选择较为有效,也比较容易稳定。
Sixteen cucumber crosses were made by using 8 inbreed lines.Among these inbreed lines,one of them showed high positive effect on average fruit weight and fruit neck length,another showed negitive effect on fruit width and flesh thickness.Among the 16 crosses,3showed higher special combining ability on average fruit weight,otherwise,3 showed lower special combining ability on fruit neck length.The narrow heredity of both fruit neck length and fruit average weight was low,however,the other traits showed higher narrow heredity.
