Studies on stigma receptivity for hybrid seed production in okra (Abelmoschus esculentus (L.) Moench)

Abstract

A field experiment was conducted during kharif 2019 to study the effect of stigma receptivity of seed parent for hybrid seed production in okra using JOL-2K-19 as male parent and JF-55 as female parent. The pollination on same day of emasculation recorded significantly the maximum number of crossed fruits retained per plant (5.48), fruit set percentage (54.78%), fruit weight per fruit (32.06 g), fruit length (19.01 cm), fruit girth (5.22 cm), hybrid seed weight per fruit (4.05 g), number of seeds per fruit (47.22), seed yield per plant (30.52 g) and 100 seed weight (6.21 g) and also seed quality parameters recorded maximum seed germination percentage (86.02%), seedling shoot length (15.11 cm), seedling root length (8.81 cm), seedling dry weight (29.08 mg), seedling vigour index I (length) (2059.24) and seedling vigour index II (mass) (2500.75) as compared to pollination one day and two days after emasculation.
