An experiment was conducted to study the effect of pollination methods on fruit set at Horticulture garden, BAU, Sabour. The effect of self, open and cross-pollination was studied in the four cultivars of litchi i.e. Deshi, Purbi, Bedana and Kasba. Five panicles/replication were bagged at flowering stage for selfing. Some panicles were tagged and left opened for open-pollination and some panicles having female flowers were bagged for making cross-combinations. It was clearly seen that in Deshi cultivar when open-pollinated having 222 female flowers, total fruit set was 47; in Purbi 314 flowers were kept for open-pollinated and in case of cv. Bedana when the number of female flowers were 141, the number of fruit set was 09 whereas in case of Kasba when 218 female flowers were left for open-pollination, the total number of fruit set was recorded to be 10. When five panicles were left for self-pollinated in all the four cultivars, the number of initial fruit set was maximum in case of Purbi (09) followed by Deshi (08), the minimum was found in Kasba (02). Due to the short time availability of flowers and lack of synchronization with respect to stages of flowering in four cultivars under study the possible cross-combinations were made. The numbers of flowers crossed in Deshi x Bedana were 60 and the number of initial fruit set was 17. Similarly Purbi x Bedana, Purbi x Deshi and possible crosses were made and it was observed that when 12 flowers were crossed in the combination Kasba x Bedana, the fruit set was nil. Similar was the case with Kasba x Purbi.
