Study entitled “Line × Tester analysis in garden pea” was undertaken to estimate the combining ability effects to find out superior cross combinations for their further exploitation. The experimental material comprises of five lines viz., Arka Uttam, IIHR-48, IIHR-34, IIHR-41, Arka Tapas and three testers viz., Arka Ajith, Arka Sampoorna and Arka Priya with their fifteen crosses along with check Arka Pramodh. The parents and hybrids were randomized separately and sown using Randomized Block Design during 2019-20. The results revealed that among the female parent Arka Tapas recorded a significant GCA effect for the most of the yield contributing character except for days taken for first picking. The highest significant desirable SCA effect was observed by the cross Arka Tapas × Arka Priya for the traits average pod weight (4.03), average green seed weight (2.40), pod yield per plant (16.12), pod yield per hectare (0.91). GCA to SCA ratio was greater than the unity for many of the traits indicating the predominance of additive gene action which can improve through recurrent selection or heterosis breeding.
