Heterosis Studies for Grain Yield In Pea (Pisum sativum L.)

The present investigation entitled “heterosis studies for grain yield in pea (pisum sativm L.)” was undertaken to estimate extent of standard heterosis, average heterosis and heterobeltios. Line x Tester mating design was selected for the study. The experimental material comprised of 3 females (lines), 8 males (Testers) and their 24 crosses. The highest significant average heterosis was recorded in cross DDR-39 X DDR-55 (23.71) while the cross Rachana X DDR-44 (20.52%) recorded the highest significant heterobeltiosis for grain yield per plant. The highest significant standard heterosis for grain yield per plant was recorded in HFP-4 X IPF-09-11 (35.71% over the check Rachana and 21.56% over the check HFP4) followed by DDR-39 x DDR-55 (23.54% over the check Rachana) and Rachana x DDR-44 (22.75% over the check Rachana).
