Abstract: Investigations was carried out at Coconut nursery, Department of Spices and Plantation crops, Horticultural College and Research Institute, TNAU, Coimbatore during the year 2014-2018 to evaluate coconut genotypes and hybrids for yield and nut quality. Fourteen genotypes were used for the study. Among the fourteen genotypes the maximum vegetative characters viz., tree height (12.10m) in Andaman ordinary, trunk girth in Chandra Laksha (103.10cm). Maximum number of functional leaves was recorded (35.92) in Andaman Ordinary. Maximum number of inflorescence per palm per year was recorded by Andaman Ordinary (13.26) followed by Laccadive Ordinary (13.06) compared to minimum values recorded by Kulasekaran Dwarf Green (10.51). Maximum number of bunches per palm per year (12.58) was recorded by Andaman ordinary followed by Chandra Sankara (12.11) compared to minimum values recorded in Kulasekaran Green Dwarf (9.01) and Malayan Green Dwarf (9.60). The genotype Laccadive Ordinary recorded whole nut weight (871.00g) and dehusked nut weight (387.61g). Kernal weight was more in Andaman Ordinary (219.62 g) whereas it was low in Kulasekaran Green Dwarf (134.914g). Andaman Ordinary is considered to be more suitable for further crop improvement programme under Coimbatore conditions.
