tailieunhanh - Heterosis for grain yield and its component traits in rice

Twenty one Kerala rice varieties were crossed with four CMS lines in LxT fashion. The hybrid developed from twenty two crosses between identified restorers and 4 CMS lines were evaluated for heterosis in yield and yield contributing traits. | 2017 6 10 50-60 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 6 Number 10 2017 pp. 50-60 Journal homepage http Original Research Article https Heterosis for Grain Yield and its Component Traits in Rice R.

The hybrid developed from twenty two crosses between identified Restorers Hybrid restorers and 4 CMS lines were evaluated for heterosis in yield and yield and Heterosis. contributing traits. Identified promising hybrids were UPRI95-17A x Article Info Aiswarya UPRI95-17A x Neeraja UPRI95-17A x Remya and CRMS31A x Kanakom based on high mean grain yield per plant and high standard Accepted 04 September 2017 heterosis over standard check Uma with respect to grain yield and yield Available Online contributing traits. Identified superior hybrids can be released for 10 October 2017 commercial purpose after trail. Introduction The challenge of increasing the annual rice and widely adopted by farmers in China production of the country calls for both short during the past 25 years. During 2006 and long term planning encompassing genetic hybrids were cultivated in India in around 1 as well as crop management options. Among and the National Food Security Mission the innovative genetic options available NFSM has set a target of expanding the hybrid rice technology is practically feasible hybrid rice cultivation to 3 by 2011-12. .
