甜菜品种产糖量及其主要构成因素稳定性的分析

Stability analysis of sugar yield and main constitute of sugar beet variety

采用俞世蓉的稳定性参数统计法与Eberhart-Russell模式分析了第五届国家甜菜品种区域试验的7个优良品种(材料)的稳定性,结果表明ai值(稳定系数)具有bi值(回归系数)相通效应。参试材料81G-68、406、83315产质量高,稳定性好,适应性广。对产糖量主要构成因素稳定性分析表明,平均产量和平均含糖率变异较大,易受环境条件影响,其中参试材料81G-6的变异系数较小,bi值也较小。

The stability of 7 better variety of the 5th stage National Sugar beet Varicly Test was analyzed through Yu shirong＇ s statistical method about stability parameter and Eberhart - Russe Ⅱ model. The results indicated that there was a positive correlation between the value of ai and bi 81G - 6,8406 and 83315 showed high yield, pretty quality, better stability and widespread adaptability. The results of stabiity analysis on sugar yield and constitute indicated that there was more variation on mean rcotyield and sugar yield, and it were often affected by environment condition. The coeffcient of variation of BIG-6 was smaller, and so be done the value of bi.
