Popis:	Field experiment was carried out to assess the genetic potential of okra genotypes through breeding and selection in 6 genotypes of four crosses (Arka Abhay × GAO-5, GJO-3 × VRO-6, Phule Utkarsha × GAO-5 and P-8 × VRO-6). Narrow sense heritability and genetic advance varied across crosses and traits. For fruit yield, narrow sense heritability were moderate and genetic advance were moderate and high, respectively for crosses viz. , Arka Abhay × GAO-5 and Phule Utkarsha × GAO-5 while both were moderate for crosses viz. , GJO-3 × VRO-6 and P-8 × VRO-6; appeared to be better indicator for selection. Among the crosses, Phule Utkarsha × GAO-5 exhibited significant relative heterosis as well as heterobeltiosis for fruit yield and its contributing traits.
