八倍体小黑麦新品种（系）区域适应性评价

EVALUATION OF REGLONAL ADAPTABILITY OF NEW OCTOPLOID TRITICALE CULTIVARS

对八倍体小黑麦６个新品种（系）１９９０～１９９２年度在贵阳、安顺、织金、威宁、江口５个生态条件悬殊的试点进行区域试验的资料进行方差分析，并按Ｅｂｅｒｈａｒｔ－Ｒｕｓｓｌｌ推荐的稳定性参数评价，确定出产量水平显著超过对照小麦阿波的劲松４９号和７３０２２－１两品种（系），年度间、试点间差异小，产量稳定性较优。

The regional adaptability of six new octoploid triticale in the multilocation trial sites with great ecological difference was conducted in Guiyang,An- shun,Zhijin,Weining and Jiankou during 199O─1992.It was identified that the yield level was higherthan that of the CK varieties Jinsong 49 and 73022-1 of A- bo significantly,accordingto the variance analysis and Eberchart- Russell′s yield stability parameter calculatingmethod.Meanwhile,the difference among the years and trial sites were smaller,andthe yield stability wa more.
