An experiment was undertaken to study relationship between various economically important traits in three populations of the okra viz, biparental (BIP) F2, single cross (SC) F2, and double cross (DC) F2 populations for the purpose of genetic improvement. The analysis of variance revealed highly significant differences for the populations under study for the characters. The association studies revealed the characters fruits length, average fruit weight, number of fruits per plant (0.929**), number of branches per plant and plant height showed significant positive association with fruit yield per plant, and also showed significant positive association among themselves. This suggested that these characters should be considered while selecting plants for yield improvement in segregating populations of okra. It was also revealed that intermating in early segregating generations of different individuals lead to release of additional variability.
