Abstract

The study evaluated the influence of open, hand and bagged pollination methods on fruit yield and quality of wild type at Ponnampet and cultivated jamun types (K-45 and N-20) at GKVK, Bengaluru, which was laid out in randomized complete block design (RCBD). Open and hand pollination resulted in significantly higher fruit set, retention and yield compared to bagging. Among wild type, hand pollination resulted in better fruit retention (48.80%) and higher pulp content, while open pollination showed better fruit quality parameters like total soluble solids and phenols. Cultivated types K-45 and N-20 also responded best to open pollination with higher fruit weight and sugar content. Bagged conditions showed negligible fruit set, confirming self-incompatibility. Differences in sugar, phenol and moisture content further emphasized the importance of pollination mode in enhancing jamun fruit quality.
