Studies on pollen viability of male parent in tomato hybrid seed production.

摘要

An experiment was conducted in Karnataka, India, during 2002 and 2003 to determine the pollen viability for hybrid seed production in tomato. In this study, pollen were stored for one, two and three days under ambient and refrigerated condition along with fresh pollen used for pollination in the production of hybrid seed of DTH-1. There was a significant variation in pollen viability due to age of the pollen and storage conditions. Pollen stored under refrigerated condition for two days were significantly superior with respect to fruit set, fruit yield, seed yield and quality compared to ambient stored and use of fresh pollen for pollination.
