Sammendrag

The experiment of two 3 x 3 complete diallele crosses was carried out with four wild river stocks (Ganga, Yarmina, Brahmaputra and Sutlej) and one fanned stock (Local) of Rohn carp (Labeo rohita). The Local stock was included in both diallele crosses. In total, 864 fish were individually tagged at 6 months of age and reared for 14 months in three monoculture and two polyculture earthen ponds in Orissa, India. For harvest weight, total heterosis for each of the six stock crosses was low or negative and average heterosis was also low and in most cases not significantly different from zero. For survival, total and average heterosis was negligible and not significantly different from zero. It is concluded that genetic improvement through crossbreeding of Indian stocks of Rohn carp has little practical significance. (C) 2002 Elsevier Science B.V. All rights reserved.
