ABSTRACT

The present study entitled “Line × Tester analysis in garden pea” was undertaken to estimate the extent of heterosis and combining ability effects for growth, yield and quality traits in pea. Experimental materials comprise 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 one check Arka Pramodh. The parents and hybrids were randomized separately and sown using a Randomized Block Design with two replications during 2019-20. The results revealed that the female parent Arka Tapas recorded a significant GCA effect for most growth and yield parameters. The cross Arka Tapas × Arka Priya exhibited a high percentage of mid-parent (38.74 %), better parent (16.70 %) and heterosis over the commercial check (9.96 %) for the character pod yield per hectare.
