Inheritance Research of Main Characters of Strawberry Fruit in Open Field Cultivation of South China

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.
