The average fruit weight, storage life and fruit core size of the seedlings of 4 crossed combinations of pear cultivars were used for studying their inheritance trends. The result showed that the inheritance of fruit weight is of quantitative character and controlled by multi-genes, The distribution of weight deviated the normal curve, the mean of offspring was smaller than the mean of the parents. The ratio of non-additive effect among the weight heritability was relatively larger than additive effect. The...
