Cotton (Gossypium hirsuitum L.) is a major cash crop all over the world. The presence of genetic variation in the available germplasm is pre-requisite for starting breeding program, secondly information about various genetic mechanism controlling various parameters is also important. The present experiment was planned to study the genetic basis of some agronomic traits contributing to yield of upland cotton. In this experiment, four genotypes viz PB-896, PB-76, AGC-2 and VH-282 were used as parents, which were crossed in all possible combinations. The F1 along with four parents was evaluated in field conditions. These progenies were planted in three replication following randomised complete block design. At the time of maturity, data were recorded on plant height, no. of bolls plant-1, boll weight, seed cotton yield and ginning out turn. The data were used for analysis of variance to test the variation among genotypes for these traits. All the genotypes were highly significant for the parameters under studied. It showed that parent AGC-2 has maximum plant height (84.30 cm) and PB-76 has minimum plant height (72.55 cm) among all the parents while hybrid AGC-2 × PB-76 exhibited maximum plant height (80.13 cm).   It revealed that parent AGC-2 has maximum number of bolls (12.00) and while hybrid PB-76 × PB-896 showed maximum number of bolls (14.00). The parent VH-282 exhibited maximum boll weight (3.34 g) and hybrid PB-76 × PB-896 showed maximum boll weight (3.58 g). It showed that parent PB-896 gave maximum seed cotton yield per plant (40.15 g) and hybrid PB-76 × PB-896 showed maximum seed cotton yield (43.40 g). It is showed that parent AGC-2 has maximum GOT (45.23 %) while hybrid AGC-2 × PB-896 showed maximum GOT (45.75 %).
