均单果重等性状在F1中广泛分离，杂种群体的平均值低于亲中值，表现明显的衰退现象，表明这3 个性状均为数

The results were as follows: Firstly, the S-locus of Katy was heterozygous, and self-compatibility was dominant to self-incompatibility. Secondly, a very extensive segregation in self-pollinated fruiting rate, fertile flower rate and average fruit weight was observed in the F1 populations, and averages of these traits were lower than that of mid-parent means. Therefore, these traits were confirmed to be quantitative.
