The study was carried out at Coconut nursery, Department of Spices and Plantation crops, Horticultural College and Research Institute, TNAU, Coimbatore during the year 2018-2021 to evaluate coconut genotypes and hybrids for growth and yield. Fourteen genotypes were used for the study. The design of the experiment was Randomized Block Design with two replications with each genotype representing three palms per replication. Among the fourteen genotypes Andaman Ordinary recorded the highest tree height of 12.13 meters and trunk girth in Chandra Laksha ((102.76 cm). Andaman Ordinary recorded maximum number of inflorescence per palm per year ((13.44)) followed by Laccadive Ordinary (13.08) and minimum number of inflorescence were recorded by Kulasekaran Dwarf Green (10.52). The genotype Andaman ordinary recorded more number of bunches per palm per year (12.52) whereas less numbers recorded in Kulasekaran Green Dwarf (9.56) and Malayan Green Dwarf (9.70). Whole nut weight (861.00 g) and dehusked nut weight (385.50 g) were recorded maximum in Laccadive Ordinary. Kernal weight was maximum in Andaman Ordinary (250.02 g) whereas it was minimum in Kulasekaran Green Dwarf (132.90 g). Andaman Ordinary is assessed to be more appropriate for further crop improvement programme under Coimbatore conditions.

Tall coconut, Andaman Ordinary, Nut, Variability.

It can be concluded from this experiment that among the coconut hybrids/varieties evaluated, Andaman Ordinary was found to be superior in terms of number of bunches per palm per year ,number of nuts per bunch and nut yield over the other varieties and Hybrids. Hence, the variety Andaman Ordinary was considered to be the most suitable for cultivation in Coimbatore conditions Identification of high yielding varieties/hybrids suitable to a particular area is very important to achieve higher production and productivity in coconut.
