Abstract : Studies on fruit set and fruit drop were carried out in Trichur, Kerala, India, on four cultivars (Alphonso, Prior, Muvandan and Neelum) and two hybrids (Ratna (Alphonso × Neelum) and H-151 (Kalapady × Neelum)) of mango during 2000-01. The season of flowering in majority of the genotypes was during December-January except in Neelum in which it was during April-May. The number of inflorescence per square metre ranged from 23.6 to 7.0 and was the maximum in Prior and minimum in Alphonso and Neelum. In the case of percentage of bisexual flowers Alphonso had the maximum (44.39%) bisexual flowers and Muvandan had the minimum. Variation in length, breadth, colour and density of inflorescence was noticed among the genotypes. Initial fruit set ranged from 5.39 to 8.45 fruits per inflorescence. Fruit drop was 50% during the initial 15 days and continued for 45 days. The maximum drop was noted in Alphonso (89.93%) and the minimum in H-151 (79.6%).
