Prospects for selective breeding of pearl oysters in India

By T S Velayudhan


Recently a variety of approaches has been introduced\ud in the field of genetics of molluscs, including Mendelian\ud genetics, cytogenetics, quantitative genetics, biochemical\ud genetics and hybridization. Wada (1975 a, b, 1985) has\ud estimated the response to selection for several attributes\ud of Pinctada fucata for sheU variance of full siblings.\ud He analysed the genetic variability and gene frequencies\ud at three loci in two strains selected for four to five\ud generations. The change of frequencies of colour of\ud nacre in the selected lines of pearl oyster to yellow\ud prismatic layer for five generations has been studied\ud (Wada, 1985). Wada (1976, 1985) and Wada and\ud Komaru (1985) have studied the chromosome\ud morphology of different species of bivalves
