摘要: 以草莓3个杂交组合F1代实生苗及亲本为材料,研究草莓平均果重、可溶性固形物含量、果实的纵径和横径性状的遗传变异及其相关性。结果表明:草莓平均果重、可溶性固形物含量、果实的纵径和横径均为多基因控制的数量性状,呈连续性变异。3个组合杂交后代果实纵径、横径、平均果重和可溶性固形物含量的广义遗传力平均值分别为0.68、0.56、0.64和0.86,表明草莓杂交后代这4个性状的差异主要是由遗传效应引起的。与亲代相比,草莓杂交后代果实平均果重和果实横径有减小的趋势,而可溶性固形物含量和果实纵径有增加的趋势;草莓杂交后代平均果重与果实纵径、果实横径均极显著正相关;佐贺清香×甜查理组合果实可溶性固形物含量与果实纵径显著正相关,丰香×甜查理组合极显著正相关;同时3个杂交组合草莓果实纵径与横径均极显著正相关。Abstract: In this experiment,three strawberry cross combinations were used to study the inheritance trend of main fruit characters,and correlations between fruit characters of strawberry were also discussed.The result indicated that the fruit weight,length,width and soluble solid content were quantitative characters with succession variance.The average broad-sense heritability of three cross combinations′fruit length,width,weight and soluble solid content traits were 0.68,0.56,0.64and 0.86respectively,which showed the difference of these fruit characters were mainly caused by heredity.As concerning the parents,the average of weight and width of F1trended to be smaller,but the average of soluble solid content and length trended mainly to be bigger.The correlation between fruit soluble solids content and length of Sagahonoka×Sweet Charlie cross combination was significantly positive correlated,and Toyonoka×Sweet Charlie cross combination was extremely significantly positive correlated.And the correlations between fruit length and width of three cross combinations were extremely significantly positive correlated.
