Evaluation of Rice Germplasm for the Development of Hybrid Rice

Muhammad Sabar and Muhammad Akhter

Abstract:
Hybrid rice varieties have shown 15-20% higher yield potential than inbred varieties. Future food security of Pakistan lies in the development of hybrid rice varieties. Procedures for developing rice hybrids are quite distinct from those employed for breeding conventional varieties. Three hundred uniform lines including sixteen (16) cytoplasmic male sterile (CMS) lines from International Rice Research Institute (IRRI), Philippines were collected to evaluate the local material for identification of restorer and maintainer lines. Furthermore, agronomic traits i.e., plant height, maturity days, number of grains per panicles, productive tillers per plant and paddy yield of these lines were also categorized. 26 restorers and 34 maintainers had been identified.
