COMBING ABILITY OF CMS AND RESTORERS IN RICE (O. sativa L.)

open access: yesBangladesh Journal of Plant Breeding and Genetics, 2013
General and specific combining ability effects were estimated from a 5 line × 8 tester crosses to explore the genetic behavior of CMS and restorers in rice. The variance for GCA and SCA showed predominance of non-additive gene action for all the ten morpho-physiological traits.
