| 摘 要： | 通过高稳系数法和农业试验统计的标准差和变异系数对贵引07-15等四个果蔗新品种区试、生产示范相关资料进行综合分析,结果表明:黔蔗00-126、贵引07-15、贵引07-16、贵引07-04在区试中,新植蔗平均产量比对照新植蔗平均产量分别增产48.15%、31.16%、26.67%、24.74%,宿根蔗平均产量比对照分别增产3236%、28.49%、34.56%和7.35%,增产效果均达显著或极显著水平;3个生产示范点平均产区试点和生产示范中都表现高产。四个品种(系)的标准差和变异系数两项指标值都很小,说明四个品种(系)变异程度小,品种适应性好;而且,每个品种(系)的高稳系数(96%

| Abstract: | Through comprehensive analysis on the production and modeling of four new sugarcane varieties including 07-15 by means of high stability coefficient and experimental statistics, the results showed that in the experimental test, the average production of new planting sugarcane Qianzhe 00-126, Guiyin 07-15, Guiyin 07-16 and Guiyin 07-04 increased by 48.15%, 31.16%, 26.67% and 24.74% compared with the control variety; the average production of ratoon sugarcane was higher than control by 32.36%,28.49%,34.56% and 7.35%, respectively. Yield increase showed a significant or a very significant difference between test and control. The average production in three production demonstration sites all presented the trend of high yields. The standard deviation and variance coefficient were very low, which indicated that the degree of variation of these four new breedings were very low with preferable adaptability. The coefficient of stability is relatively high(96%
