摘要/Abstract

摘要： 本文以每穗小穗数可多达37个的不分枝普通小穗品系“10-A”为母本，与一系列遗传差异较大的测验系组配的20个组合的P1、P2、F1、F2、B1和B2六个世代为供试材料，考察了“10-A”最优良的性状（小穗数）和3个突出的不良性状（抽穗期、穗粒数和粒重）。采用明道绪最近提出的“利用各世代的小区平均数估计遗传参数的加权最小二乘

关键词: 小麦，多小穗，基因效应，加权最小二乘法，相关分析

Abstract: The tested line“10-A” is a common wheat (Triticum aestivum L.) multispikelet line which has 30-37 spikelets per spike, but late maturity, less grain number per spike and low 1000 grain weight, “10-A” was crossed with a set of 20 tester lines which had great genetic diversity in various character

Key words: Wheat (Triticum aestivum L.), Multispikelet, Gene effect, Method of weighted least squares, Correlation analysis
