The present study aimed to study the embryo sac development (ESD) before anthesis and 1 and 7
days after self and cross pollination and parthenocarpic ability to understand the seedless fruit
development in Kagzi Kalan lemon.The results of ESD showed normal female gametophyte of Kagzi
Kalan lemon, as large percentage of normal ovules (60.16 to 66.67%) with no sign of degeneration
had been observed in the pistils collected before anthesis and 1 day after pollination (DAP). Further,
ESD studies also showed significant differences in number of fertilized and unfertilized ovules
after 7 DAP. The highest percentage of fertilized ovules (71.39%) was observed under cross pollination
treatments. Whereas, under self-pollination treatments, no sign of fertilization was observed and
most of the ovules had degenerated or disappeared nuclei.The results of fruit set at 7 DAP showed
100% fruit setting under all treatments. Whereas, at 20 DAP, highest fruit set was recorded in Kagzi
Kalan × Kagzi Kalan cross (94.50%) however, highest retention of fruits (53.61%) was observed
under Kagzi Kalan × Kagzi lime. Self-pollination of Kagzi Kalan resulted into production of seedless
fruits, whereas cross pollination treatments produced 100% seeded fruits. Notwithstanding, pollen
parents also influenced physicochemical quality of fruit in Kagzi Kalan.
