A field study with diallel analysis (excluding reciprocals) in cucumber using cross combinations of salinity-tolerant and -sensitive inbreds indicated that the mean square due to gca and sca were significant in desirable direction for all the characters. The higher sca values than gca and, PR and ADD values <0.5 and >1, respectively indicates the predominance of non-additive gene effects in the expression of characters and accordingly hybrids development was rewarded. The potential cucumber hybrid CRC-8 x Pusa Uday and CHC-2 x Pusa Uday were found superior for earliness, yield and its attributing traits based on high sca effects and could be exploited in saline areas of our country.
