基于能源利用的高粱配合力和杂种优势分析
Combining ability and heterosis of sorghum for biomass energy
摘要
Abstract
One of the breeding objectives of sorghum（Sorghum bicolor L.Moench）is to obtain high biomass yield.Fifteen different types of sorghum R lines and four male sterile lines were used to analyze the combining ability and heterosis of 11 traits with NCⅡ genetic mating design mating scheme.The results indicated that lodging percentage was controlled additive effects;other traits such as aboveground biomass were contributable to both additive and non-additive effects.Those parental lines of NW-21,Lvneng-3 and maternal parental line of A3Jinliang-5A with higher general combing ability for the aboveground biomass were identified as potential parental materials for high biomass hybrid breeding program.The two crosses of A3Sanchisan A×Lvneng-3 and A3Sanchisan A×Saccaline revealed significantly higher aboveground biomass than that of A3Sanchisan A×Rio（check）.Hybrids displayed over-standard heterosis in aboveground biomass.关键词
