Abstract: Coconut has a long productive period hence, selection of quality materials are of utmost important for increasing the productivity in coconut garden can be increased by improving the genetic potential. An evaluation trial was done under AICRP on Palms at Horticultural Research Station, Mondouri, Bidhan Chandra Krishi Viswavidyalaya, West Bengal to evaluate the performance of seven cultivars of coconut namely - Philipines Ordinary, Laccadive Ordinary, Andaman Ordinary, Laccadive Micro, S S Green, East Coast Tall, West Coast Tall and three hybrids namely COD x WCT, WCT x COD and MYD x WCT during 2004 and 2005.The materials were supplied from CPCRI and planted in 1986 spaced at 7.5 x 7.5 m. in RBD with 3 replication and 4 plants for each treatment. It was observed that the bunch production was maximum in hybrid COD x WCT (9.4 palm-1) followed by Philippines Ordinary (8.4 palm-1). The nut yield per palm was recorded maximum (105.2 palm-1) in Laccadive Micro followed by 92.6 palm-1 in COD x WCT. The copra yield was highest in COD x WCT (9.3 kg) followed by Laccadive Ordinary (9.2 kg ). The hybrid CODXWCT (Chandrasankara), Lacadive Ordinary, Lacadive Micro and Philipines Ordinary performed better than the other cultivar or hybrids in West Bengal.
