Abstract: The most important fruit of the Sapindaceae family is Litchi (Litchi chinensis sonn). It originated in China and is widely distributed in the tropics and subtropics (Knight, 1980). Litchi is an important sub-tropical evergreen fruit crop. Therefore, the present investigation entitled “Study of pollen viability and Pollen germination in different cultivars of litchi in sabour, Bhagalpur condition” was carried out during 2017-18 in the Department of Horticulture (Fruit and Fruit Technology), BAC, Sabour,. For this experiment four litchi cultivars viz., Purbi, Bedana, Shahi and China were chosen for the present study. On the basis of data recorded on the pollen viability and germination percentage is maximum in cv. Purbi (87%, and 83.40%) and minimum was observed in cv. China (78%, and 74%).This might be due to genetic composition and environmental factor. The date of fruit-set in different cultivars of litchi under study varied from 13-03-2018 to 25-03-2018. The maximum duration of fruit set was noticed in Purbi (9.8 days) followed by Shahi (8.26 days). Among the four cultivars, fruit set was recorded to be highest in case of Purbi X Bedana (20) followed in Desi X Bedana (17).
