|Outline of Final Research Achievements
Using an F2 population from a self cross of F1 between European pear ‘ Max Red Bartlett’ and Japanese pear ‘Osa Nijisseiki’, we constructed integrated genetic linkage map consisted of SSR markers derived from largescale information of apple, European pear and Japanese pear. We also performed quantitative trait locus (QTL) analysis of brown spot disease susceptibility and resulted in making SSR markers linked to its susceptibility. The molecular mechanism of parthenocarpy has not understood yet. Here, we have searched genes related to parthenocarpic fruit in pear by RNA-seq analysis. Expression of several trans factors genes showed strongly correlated to the development of parthenocarpic fruit. These candidate genes were selected for further transgenic experiment to clarify the role of parthenocarpy.
