摘要
为深入研究和评价烤烟新品种的丰产性、稳定性和品种生态布局,通过引入新型分析工具GGE模型,对2011年中间香型烟叶产区7个试点、11个烤烟新品种(系)的产量和产值进行了直观比较分析。结果表明,GGE双标图解释了产量总变异的71.9%和产值总变异的64.4%,具有真实代表性。GGE双标图显示,参试材料间丰产和稳产性差异很大,有些材料对某些环境具有特殊适应性。11个新品种(系)中,毕纳1号和贵烟1号总体表现为丰产、稳定和广适,同时毕纳1号、秦烟98和HB032分别为区1(遵义、武隆、桑植)、区2(旬阳、蒙阴)和区3(贵定、咸丰)的丰产新品种(系)。这为中间香型烟叶产区烤烟新品种的筛选和评价提供了借鉴。
In order to evaluate the yield ability, stability, and eco-distribution of tobacco cultivars effectively, genotype main effect and genotype-environment interaction （GGE） biplot was introduced as a new and powerful approach to analyze the leaf yields of 11 flue-cured tobacco （cultivars or lines） tested at 7 planting areas of middle flavor type. The results showed that the GGE biplot was highly representative, which explained 71.9% of the total variation of production value and 64.4% of the total yield variation. The cultivars with highest yields and of most stability and most adaptability were ＂Bina 1＂ and ＂Guiyan 1＂. The 7 test sites were broadly classified into 3 environments, as region one including Zunyi, Wulong, and Sangzhi, region two including Xunyang, and Mengyin, region three including Guiding and Xianfeng, in which the best genotypes were ＂Bina 1＂, ＂Qinyan 98＂, and ＂HB032＂respectively. The result of some genotypes specifically adapted to certain environments is useful for special cultivars screening.
