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

| 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. |
