Investigation was carried out at Coconut Research Station, Tamil Nadu Agricultural University, Aliyarnagar, during 2015-2017 to study the performance of indigenous and exotic coconut genotypes for yield and nut quality. Wide variations on vegetative parameters were observed within the genotypes. Among the nineteen genotypes the maximum vegetative characters viz., palm height (15.70 m) in Java Tall, trunk girth (1.26 m each) in FMS and Andaman Gaint, number of functional leaves (38.25) in Ceylon tall, petiole length and length of leaflet bearing portion (1.53 m and 5.84 m) in Nadora Tall and number of inflorescence per palm per year (14.16) were recorded in Seychelles Tall. The maximum number of bunches per palm per year and nut yield per palm per year were recorded by Seychelles Tall (13.36 and 211.50, respectively) compared to minimum values recorded by Tiptur Tall (10.13 and 67.25). The maximum nut characters namely whole nut weight (1999.50 g), dehusked nut weight (1323.00 g), kernel weight (510.00 g) and copra content (390.50 g) were recorded by Andaman Giant. However, the maximum nut husk weight was recorded by San Roman (677.50 g) compared to lowest recorded by Arasampatti Tall (187.00 g). Though, the number of nuts was maximum in genotype Seychelles Tall but considering to the quantitative and qualitative characters it revealed that genotype Andaman Giant performed better than other genotypes.
