Exploitation of Heterosis for Yield, Yield Components and Quality Traits in Rice (Oryza sativa L.) Using Line × Tester Mating Design
Increasing grain yield remains a primary objective in rice breeding to ensure global food security. Heterosis, which exploits the superiority of F₁ hybrids over their parents, is among the most effective genetic tools for achieving yield gains. The present study was conducted at the Regional Agricultural Research Stati...
