The flowering, Pollination and Hybridization of Groundnuts (Arachis hypogaea L.)

The flowering pattern, emasculation and pollination of loc.ally grown groundnuts were studied. Flowering generally occurred between 0645 to 0900 h with a half hour delay on dull days. Anther dehiscence occurred itl- the bud about one hour prior to blooming. Pollen tube growth was approximately 1...

description The flowering pattern, emasculation and pollination of loc.ally grown groundnuts were studied. Flowering generally occurred between 0645 to 0900 h with a half hour delay on dull days. Anther dehiscence occurred itl- the bud about one hour prior to blooming. Pollen tube growth was approximately 1 em per hour and fertilization was estimated to take place 5 to 6 hours after pollination. There was no improvement in pod set following tripping of the flowers although it was found that assisted pollination improved peg formation over natural self-pollination. Emasculations can be carried out either using forceps or suction on the afternoon prior to the day of anthesis without any detrimental effect on the success of cross-pollination. Some cross-combinations and parents were capable of higher success in cross-pollinations than others.
