ABSTRACT

Evaluation of Bt. cotton at Dharwad (Karnataka) indicated that Bt-cotton genotypes were far
superior than non Bt genotypes and local check DHH-11. They have produced 41 to 66 per cent
higher yield than DHH-11 hybrid. Among the three Rasi Bt cotton hybrids, RCH-2 Bt cotton was the
top yielder and it gave 5-17 per cent higher yield than other Bt-genotypes. Bt-hybrid RCH-144 Bt
recorded 71 per cent increase in boll-number over DHH-11. However, there was no significant
difference for number of seeds per boll, number of monopodia, number of sympodia, plant height
and per cent bollworm incidence among Bt, non Bt and commercial check and the higher yield was
attributed due to more number of bolls per plant.
