甜瓜产量相关性状的灰关联综合分析研究

Grey relational grade analysis on yield characteristics of inbred melons

运用灰色关联度分折法分析了甜瓜14份自交系材料的7个产量性状,研究了甜瓜主要性状对产量的影响.结果表明各性状对产量影响的大小依次为:单瓜重>病情指数>横径>果实可溶性固形物含量>纵径>果实生育期>全生育期。优质高产育种中应选择单瓜重量大、抗病的材料作亲本。

Seven yield characteristics of 14 inbred melon lines were analyzed using grey relational grade analysis method to determine the correlation between the characteristics and yield of the melons. The results showed the rankings of these 7 yield characteristics were： single fruit weight〉disease index〉horizontal diameter〉soluble solid content〉length〉fruit growing stage〉 total growth period. It was concluded that high individual fruit weight and disease resistance should be the indices for parent selection in breeding the melon.
