Induction of gynogenetic haploidy in oyster Crassostrea gigas, using ultra violet irradiated sperms
Description
Eggs of Crassostrea gigas were fertilized with sperms exposed to different doses of UV irradiations by keeping a constant rate of 121.47 ergs.mm-2sec-1 and changing the period of exposure from 4 to 90 sec. Samples of larvae were analysed for chromosomal ploidy, rate of fertilization, developmental and chromosomal abnormalities. The gynogenetic haploid larvae first made their appearance in the 30 and 50 sec group exposed to 3644 and 6074 ergs mm-2 UV. The maximum number was found in the 90 sec group exposed to 10932 ergs mm-2 UV. (author). 11 refs., 1 tab., 1 fig
