Combining Ability Studies in Cucumber (Cucumis sativus L.) under Salinity Condition

Abstract

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.
