Abstract:

The present investigation was undertaken to estimate the extent of heterosis for yield and its quantitative traits in crosses of G. hirsutum. For this purpose, two hybrids were developed by using four parents during kharif 2014. These hybrids along with four parents were planted in kharif 2015. The hybrids DSMR10 x DRCR4 and DRGR2572 x M5 exhibited significant positive heterosis over mid parent and better parent for seed cotton yield and lint yield. These hybrids also showed significant heterosis for plant height, number of bolls per plant, boll weight, lint yield, number of monopodia and sympodia per plant.
