摘要
通过对省内120个县市的720份资源的主要数量性状分析,结果表明:千拉重、穗粒重和穗粒数是影响高梁单产的主要性状。但千粒重通过穗粒数对产量的间接效应是一个很大的负值,说明我省地方品种的大粒类型并非是高产类型。
This paper analyzed the main quantity characters of 720 varieties in 120 counties of Sichuan Province. The results indicated 1000—grain weight, grain weight/panicle and spikelets/panicle were the main traits which affected sorghum yields. 1000—grain weight was negative influence on yields. So the type of big grains in local sorghum varieties maynot be high in yield.
