The study was conducted at Halani District Naushehro Feroze during the kharif season 2013-14, to investigate the heterosis and heterobeltiosis of five parents through diallel cross combination to evaluate the superior parents and cross combinations for knowing the potential to produce F1 hybrids for hybrid crop development. The analysis of variance revealed that significant difference among the parents and genotypes, which suggested that the occurrence of extensive amount of genetic variability for all the characters studied. For number of bolls per plant hybrid MNH-886 X CIM-511 recorded more bolls over mid parent, while CRIS-134 X MNH-886 was given highest number of bolls over the better parent. The hybrid MNH-886 X CIM-506 obtained highest heterosis for boll weight and seed cotton yield per plant over mid and better parents. Whereas hybrid CRIS-134 X BH-36 produced maximum seed index heterosis over mid parent and hybrid CRIS-134 X CIM-511 for better parent. The maximum heterosis of GOT was obtained by hybrid (CRIS-134 X CIM-506 and MNH-886 X CIM-506) CRIS-134 X CIM-506 over mid parent and MNH-886 X CIM-506 for better parent. Therefore results suggested that hybrids may be exploited in hybrid seed production.
