Abstract
A diallel programme with 36 crosses and nine parents was undertaken to analyse the general and specific combining abilities (gca and sca) of nine coconut cultivars of diverse origin, .and their hybrids, for five important characters. Results of diallel analysis showed that girth, height, total leaf production and leaf production during the year, were significant among the characters studied. The cross combinations, Laccadive Ordinary x Jamaica, and Fijix Jamaica exhibited high, sea effects for total leaf production and leaf production during the year. Laccadive, Jamaica, Java, Fiji and San Ramon cultivars proved useful as parents among the Tall cultivars. The D X T and T x D crosses involving , . Gangabondam as the dwarf parent flowered early. The total leaf production was also high in these crosses. In TxT crosses, JavaxSS Gteen, Laccadive Ordinary x Jamaica, .and Fiji x Jamaica flowered early.
