甜菜不同类型品种适应性稳定性分析

Analysis of Adaptability and Stability in Sugarbeet Varieties of Different Types

利用黑龙江省甜菜品种3年11点次区域试验结果,对各类型品种产质量进行联合方差分析及稳定性分析表明:年份、地区与基因型交互作用显著,不同品种对环境变异的反应趋势和程度有很大区别;平均产糖量显著高于对照品种并呈超稳定性的品种有V_(12)(3n,83316)、V_(20)(M2n,8246)和V_1(M3n,8107);不同品种类型,以雄不育二倍体和普通三倍体适应性最强,普通二倍体次之,遗传单粒种无突出表现。

Utilizing the results of sugarbeet varieties regional test have been worked in eleven regions of heilongjiang for three years to analyse the united variance and stability of yield and quality of different types varieties, the results indicated that. The interactions between years, region and genotype are signifieant and the reaction of the trend and level of different varieties, on enviro-mental variation have greatly differences; Mean sugar yield of the V12 (3n, 83316), V2 (M2n 8246) and V1 (M3n, 8107) are higher than coatrol varieties and belong to ultrastability varieties; The adaptabilities of the male steribility diploid and common triploid are the most strong in the different type varieties and the common diploid is quite stronger, but the genetic monogerm species have no outstanding expression.
