Abstract: Okra is a tropical and subtropical regional crop that belongs to the family Malvaceae. An experiment was conducted to identify the transgressive segregants for yield and yield contributing characters in F2 population of three crosses in Okra. In most of the transgressive segregants of three crosses, better parent (increasing parent) yield was transgressed concurrently with the transgression of one or several other trait. Simultaneous transgression of fruit yield per plant with plant height, number of nodes on main stem, fruit length, fruit weight and number of fruits per plant was observed more frequently. One could conclude that either these attributes were necessary for fruit yield or that there was linkage drag in the genes causing these traits, which caused the genes controlling these traits to be inherited together. The most promising transgressive segregants viz., transgressive segregants No.88, 211, 258 of cross C1, No. 204, 297 of cross C2 and No.63,114 of cross C3, transgressed fruit yield per plant in addition to the higher expression of other five or six characters than the better parent in F2 generation. They surpassed their respective increasing parents in regards to fruit yield by 36.95 (Cross C1), 40.00 (Cross C2), and 33.37 (Cross C3) percent.
