摘要
对国内外194份甜高粱品种进行了10个主要农艺性状调查。采用主成分分析,发现穗重、生育期、生物产量、穗长、茎粗、分蘖及含糖量等7个因子为农艺性状的主成分。在甜高粱育种中应加强生物产量选择,适当考虑含糖量及生育期,但穗重、分蘖和茎粗不宜过高,并且穗长越短越好。研究结果将为甜高粱的品种改良和创新提供理论依据。
Ten agronomic traits of 194 sweet sorghum varieties from domestic and foreign countries were investigated.Panicle weight,growth period,biomass weight,panicle length,stem diameter,tiller,and sugar content were analyzed as the main components of agronomic traits.For sweet sorghum breeding,it needs to select higher weight of biomass and panicle,proper sugar content and growth period,fit tillers and stem diameter,and shorter panicle length.The investigating information is provided for germplasm improvement and sweet sorghum breeding.
