Outline of Final Research Achievements

To overcome some problem in pepper produciton, physiological and genetical studies of the fruit setting and enlargement of pepper were conducted. Using various fruiting characters of pepper, we clarified that the fruits setting and enlargement are involved in plant hormone cytokinin without the similarity to that of tomato.
Examination of fruiting phenotype of newly finding potent parthencarpic line "CNPH2622" clarified that have higher in fruit enlargement but not in fruit setting abilities. Therefore, to develop parthenocarpic pepper, futher studies must be needed.
