Studies on Stigma Receptivity of Female Parent in Tomato Hybrid Seed Production

Abstract

A field experiment was conducted during rabi 2002 and 2003 at Agricultural Research Station, Hanumanamatti of Haveri District in Karnataka to ascertain the peak period of stigma receptivity of seed parent (Arka Alok) in DTH-1 hybrid seed production. The pooled data had indicated that the pollination on two days and three days after emasculation of flowers recorded higher fruit set (53.01 and 55.89%), crossed fruit yield (2124 and 2406 g/plant), seed recovery per cent on net weight basis (4.19 and 4.46) number of seeds (87.56 and 96.68) per fruit, seed yield (10.93 and 11.72 g) per plant and seed quality such as germination (93.73 and 94.93%), seedling vigour (1594 and 1709) and field emergence (89.35 and 90.13%) as compared to the pollination on same day, one day, four day and five days after emasculation.
