nut yield significantly higher than the best standard check variety (BPP 8).
In the present study, B27 could be sorted out to have many desirable agro-economic traits e.g., plant height, trunk
girth, canopy spread (N-S), number of flowering laterals/m
2
, proportion of perfect flowers, sex ratio, nut weight,
kernel weight, shelling percentage, apple weight, panicle length, panicle breadth, nuts/panicle and nut yield. On
similar consideration, Cashew hybrids e.g., A71, C41, H6, H8 and D-19 could be selected for further breeding
programme to improve specific agro-economic traits. H-6 had more canopy spread in North-South direction. This
was also promising for trunk girth, total number of flowers and nut yield (kg/plant and tons/ha). In contrast J -12
had shown more canopy spread in East-West direction along with higher mean performance for other desirable
agro-economic traits e.g., trunk girth, number of perfect flowers, percentage of perfect flowers and nut yield
(kg/plant and tons/ha). Panicle length and breadth determines total number of flowers. The cashew hybrids e.g.,
B6, B27 and C44 had shown significantly broad and longer panicles compared to the best standard check variety
(BPP8) for the trait. The erstwhile mentioned high yielding cashew hybrids (D19, H6, B27, A71 and G8) had also
shown their promising status for most of the important nut yield component traits. The elite entries identified in
this pursuit may be utilized as donors in future breeding programme.
