The effectiveness of intermating or biparental mating (BIPs) was compared with
conventional selfed generations (F2 and F3) in three intervarietal crosses viz., JGL 384× …

Biparental progenies of three crosses, PMK2/Norungan, PMK2/Mattaikar and
PMK2/Poongar, involving upland rice cultivars were evaluated in Tamil Nadu, India in 2003 …

Rice (Oryza sativa L.) Page 1 Electronic Journal of Plant Breeding, 3(2):830-834 (June 2012) …

Substantial increase in rice (O/yza sativa L.) production can be achieved only with the use of
suitable hybrids. The main objective of this investigation was to identify good general and …

Eight parents of aromatic rice were crossed in half diallel mating design without reciprocal
including parents. The parents were evaluated foreleven different characters. Genetic …

An experiment of 2 line x 13 tester mating design was conducted to study the heterosis as

The two line system of heterosis breeding (S x R) in rice is a new approach for further
increasing crop yields. An attempt was made to identify heterotic combinations among the …

In view to invigorate hybrid rice breeding and exploration of heterosis in untapped, low
