| Abstract: | In order to have a comprehensive understanding of the production characteristics of the new hybrid rice cultivar Guifengyou 785,and guide the application in production,variation coefficients,Shukla variance analysis and high-stable coefficient method were employed to analyze the yielding ability,stability and adaptability of Guifengyou 785 and the control Zhongyou 169 with regional tests data during 2013-2014.Results:Yielding ability,stability and adaptability of Guifengyou 785 were significantly better than the control,and the comprehensive traits were excellent.It had a high yield potential under beneficial environment and could keep stable in poor conditions.It is an ideal new high yield hybrid rice cultivar. |
