ABSTRACT
The combing ability and standardard heterosis studies involving 11 lines and three testers were carried out for 12 characters in bell pepper. The variances due to SCA and GCA showed the non-additive gene action was predominant though the additive component was also significant. Among testers, Arka Mohini was good general combiner for no. of fruits/plant (1.77), yield/plant (kg) (0.58), average no. of locules/plant (0.26), average fruit weight (g) (24.98), pericarp thickness (mm) (0.45). Among lines, IIHR-3341 was good general combiner for yield/plant (1.05) and fruit weight (50.08). The cross Arka Gaurav X IIHR-4103 was shown highest sca for plant height (11.57), the cross Arka Mohini X IIHR-4034 was shown highest sca for no. of fruits/plant (2.50) and the cross Arka Mohini X IIHR-3341 was shown highest sca for both yield/plant (1.05) and fruit weight (51.0). The findings on standard heterosis revealed that the crosses Arka Mohini × IIHR-4103, Arka Mohini × IIHR-3341, Arka Mohini × IIHR-4107 and Arka Basant × IIHR-4096 were identified as the best heterotic cross combinations.
