Heterosis Studies on Grain Yield and Yield Attributes in Rice (Oryza sativa L.)

T. Ramakrishna, I. Swarnalatha Devi, D. Shiva prasad, M. Shankar & D. Supriya · International Journal of Environment and Climate Change · 2023

The present study was carried out to determine the best heterotic combinations in terms of grain yield and its attributes in rice. For this, 5 lines are crossed with 2 testers in the Line x Tester mating design and their F1s are evaluated along with their parents and checks in ra...
