摘要
通过双列杂交方式,对6个小麦品种的单株产量进行了一般配合力和特殊配合力效应分析。结果表明,豫麦10号单株产量的一般配合力较高,除与西安8号的差异不显著外,与其它品种一般配合力效应间的差异均达极显著水平。在特殊配合力方面,豫麦10号与陕农7859、冀麦5418与偃师4号较高,与其它杂交组合单株产量的特殊配合力效应差异达显著或极显著水平。
The diallel cross was used to analyses GCA and SCA effects for single plant yield in six wheat genotypes. The results show thatthe GCA effect of single plant yield is higher for Yumai 10. and the differences between Yumai 10. and eath other genotypes are highly significance except Xian8. The SCA effects of single plantyield for crosses ( Yumei 10. x Shan nong 7859. ) and ( Jimai 5418. xYian si 4. ) are higher and the differences are signicance or highlysignificance with other crosses.
