Abstract
The observations were made on 100 accessions of cashew germplasm on flowering behaviour, fruit set, sex ratio and fruit drop.
Apart from three flowering phases viz. male phase, mixed phase and second male phase about 50 per cent of the accessions showed bisexual phase initially.
The duration of flowering in a panicle varied from 42–123 days while in about one thrid of accessions it varied between 61 – 70 days.
The bisexual flowers in a panicle ranged from 0 · 42 per cent while in 46 per cent of accessions it ranged between 1 – 5 per cent.
Among the observations made less variation was noticed in duration of flowering, duration of mixed phase and percentage of male flowers in mixed phase.
Maximum variability was observed in mean fruit set and percentage of flowers in first male phase.
