Pollen fertility at different flowering times and its effect on seed setting of some bitter gourd (Momordica charantia L.) varieties in Ho Chi Minh city

Abstract

In the hybridisation process, pollen grains directly participate in the process through flower pollination. Pollen grain quality determines fruit formation and
seed setting. In this study, the pollen grains of the local bitter gourd variety (BD2) and F1 commercial variety were collected at 8 different flowering times (8-11h30) for fertility evaluation in the 2020 Spring-Winter crop season in Ho Chi Minh city...
