The increasing demand for baby corn intended us towards the development of single cross hybrids for baby corn speciality traits. The experiment consisted of the crossing of nine lines with three testers in line × tester mating design where the layout of the field was done under RCBD design with two replications at the University of Agricultural Sciences Dharwad during Kharif season 2019. The parental material consists of F4 generation lines belonging to one heterotic group whereas the testers were derived from another heterotic group, representing sufficient genetic diversity and genetic distance between both lines and testers along with two commercial checks HM-4 (National baby corn check) and CPB 468 (Private hybrid). The line BBCP-27-1(L2) was identified as the best general combiner for various baby corn traits such as the number of ears per plant (Prolificacy), cob weight with husk (g), cob weight without husk (g) and baby corn yield without husk per plant (g). The estimates of specific combining effects indicated that the hybrid BBCP-11-1× BBCH-51-2 showed desirable sca effects for cob weight with husk (g), cob weight without husk (g), ear length (cm) and baby corn yield without husk per plant (g). The preponderance of both additive and non-additive gene action was observed for baby corn traits indicating the scope of operation of the selection force.
