基于R语言GGE双标图的辽宁地区薄皮甜瓜品种2年区域试验产量分析

Yield analysis of muskmelon varieties in Liaoning regional test for 2 years based on R language GGE biplot

为了综合评价2年甜瓜区域试验品种基因型及基因与环境的互作关系,为甜瓜品种区域试验和育种工作提供理论依据,应用GGE双标图对2年甜瓜区域试验品种多点产量数据进行分析。结果表明,堪甜98和金凤凰9号是兼具丰产性和稳产性,并具有广泛适应性的优良甜瓜品种。试点分析表明,5个试点存在或强或弱的正向相关性,2020年和2021年5个试点分为2个和3个生态亚区。2020年盘锦、2021年沈阳试点是兼备区分力和代表性的较为理想的试点环境,可以用于筛选高产稳产甜瓜品种;丹东试点是具备强区分力的种植环境,可以用来淘汰不稳定甜瓜品种,但是不能筛选稳产的优良品种。GGE双标图能直观展示甜瓜品种的丰产性和稳产性,确认参试品种的生态适应区域,鉴别试点环境的区分能力和目标生态区的代表性,在甜瓜的种植推广工作中具备一定的参考价值。

In order to comprehensively evaluate the genotype of melon varieties in two-year regional test and the interaction between genes and environment, and to provide theoretical basis for melon variety regional test and breeding, GGE double plot was used to analyze the multi-point yield data of melon varieties in two-year regional test. The results showed that Kantian 98 and Jinfenghuang No. 9 were excellent melon varieties with high and stable yield and wide adaptability.The analysis shows that there is a strong or weak positive correlation among the five pilots. The five pilots are divided into two and three ecological subregions in 2020 and. Panjin in 2021 and Shenyang in 2021 are ideal pilot environments with both discrimination and representativeness, which can be used to screen melon varieties with high and stable yield.Dandong pilot is a planting environment with strong discrimination, which can be used to eliminate unstable melon varieties, but can not screen excellent varieties with stable yield. GGE double plot can directly show the high and stable yield of melon varieties, confirm the ecological adaptation areas of the tested varieties, and identify the distinguishing ability of the pilot environment and the representativeness of the target ecological areas, which has certain reference value in melon planting and extention.
