GENETIC INVESTIGATIONS IN GOWLI BUFFALOES OF KARNATAKA

摘要: Morphological traits and body measurements were recorded in 129 Gowli buffaloes. The average height at withers, length, heart girth 124.9 ± 1.20 124.0 1.73 cm, 136.1 1.51cm 129.3 4.51 189.4 2.11 cm 171.0 7.00 206.9 1.86 177.0 4.65 for adult females above four years breeding bulls, respectively. Chromosome analysis of buffaloes revealed a modal chromosome number 2n = 50. karyotype comprised 5 pairs submetacentric 19 acrocentric autosomes pair sex chromosomes. X was the largest acrocentric. Y identified as smallest mean relative length (%) varied from 1.70 0.09 to 7.90 0.17. approximately equal that 4 autosomes. centromeric index value highest fifth lowest first banding patterns close agreement with G-band features reported earlier river type RAPD performed on 50 animals each South Kanara using 10 random primers by PCR technique. Eight (ILO 868, ILO 876, OPG 05, OPG11, 13, OPAV 15, OPAX BG 28) found produce moderate high polymorphism than All fragments observed detected An additional fragment 918 bp primer 11 only Primers 876 28 useful differentiating buffaloes, being choice.
