Abstract
Citrus cultivars were explored for seed development in response to genotype and plant sides. Number of developed, under-developed and shrivelled seeds per berry per cultivar was found different. Kinnow showed the highest number of shrivelled seeds 3.7 per berry compared with Feutrell’s early, Musambi and Succari cultivars that ranged 2.1-2.4 seeds per berry. The interaction of different plant sides i.e., east, west, north and south with seed development and number has shown a significant impact. Sweet orange cultivars showed better root and shoot growth In vitro compared to mandarins.
