The search of genetic resources for parthenocarpic pears and comparison of gene expression between high and low parthenocarpy cultivars

ABSTRACT: Parthenocarpy—the production of seedless fruits without fertilization—is very useful for fruit cultivation. Among pear cultivars (Japanese, Chinese, and European pears and their interspecific hybrids) subjected to flower emasculation and left unpollinated, only some of the European pears had a stable and high degree of fruit set and fruit enlargement. Almost all the enlarged fruits formed no seeds. Comparison of fruits produced by using emasculation without pollination or with self-pollination ruled out the possibility of stenospermocarpy in these parthenocarpic pears. The results suggested that the abovementioned characteristics were inherited maternally by the next generation and that it should be possible to introduce parthenocarpy into Japanese pears. Neither Chinese nor Japanese pears
