The material for the study consisted of twenty genotypes of Bhindi, which were grown in a Randomized Block Design (RBD) with three replication under six environments (three different dates of sowing in Spring-summer and Kharif). The observations were recorded on five randomly selected plants for characters viz., plant height (cm). no. of branches per plant, days to first flowering, days to first harvest, number of fruits per plant, fruit length (cm), fruit diameter (cm), fruit weight (g), fruit yield per plant(kg) and fruit yield per plot(kg). Since many of the plant economically important characters are quantitatively inherited and highly influenced by the environmental condition. Phenotypic variation results from complex of three variables viz., genetic, environmental, and genotype X environment (GXE) interaction, hence, the stability of the genotypes in the predictable and unpredictable environments is an important factor for realizing the maximum yield. Since, precise information was not available on stability of promising genotypes in Bhindi that can be relied upon. Therefore, the present investigation was done on estimation of stability parameters of the genotypes for different traits in Bhindi to find out the performance of different genotypes, nature and magnitude of variability present under different dates of sowing in different crop seasons (Spring-Summer and Kharif) and to observe the stability of performance of various promising genotypes under different environments in both the seasons. The results thus indicated that genotypes HRB-9-2, Pb-57, HOE-202, D-1-87-5, Pusa Sawani, 71-14, KS-312 and D-1-87-16 had higher potentialities over environments for producing high yield. The genotypes HRB-9-2, Pb-57, HOE-202, D-1-87-5 and Pusa Sawani had average response and are highly stable for fruit yield per plant. These genotypes are likely to perform well in all the environments of both the seasons (Spring-Summer and Kharif season). Thus genotypes as identified in the present study can further be exploited for higher yield and also in breeding for superior and stable genotypes of Bhindi.
