摘要
为全面了解杂交水稻新品种贵丰优785的生产特性,指导其生产应用,利用2013—2014年贵州省水稻区域试验数据,通过变异系数、Shukla方差分析和高稳系数分析等方法,对贵丰优785及对照品种(中优169)的丰产性、稳产性和适应性进行比较分析。结果表明:贵丰优785的丰产性、稳产性和适应性均明显地优于对照品种,综合性状优良,在有利环境条件下具有较高增产潜力,在条件较差的环境中稳产性好,是较为理想的高产杂交水稻新品种。
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.
