Abstract

ABSTRACT Due to increasing farmers’ attention to sorghum (Sorghum bicolor (L.) Moench) cultivation in arid and semi-arid regions, it is necessary to introduce new, suitable sorghum cultivars. The present study aimed to evaluate the yield stability of grain sorghum genotypes via AMMI and GGE biplot analyses to identify high-yielding and best adapted genotypes for release in Iran’s warm-temperate regions. Seven promising grain sorghum lines (KGS15, KGS19, KGS23, KGS25, KGS27, KGS32, and KGS36), along with three commercial cultivars (Kimiya, Payam, and Sepideh), were studied in seven regions of Iran (Karaj, Isfahan, Gorgan, Birjand, Shiraz, Zabol, and Hamedan) during the 2019 and 2020 growing seasons. AMMI analysis showed that genotypes G7, G3, and G6 had the lowest AMMI stability values (ASV). GGE biplot analysis showed that genotype G6 had the highest grain yield (GY) in most environments, whereas genotype G1 was specifically adapted to the Hamedan province. According to the average-environment coordination of the GGE biplot, genotype G6 was the most desirable genotype, significantly better than the second and third best genotypes G4 and G3 (G4 was missed by AMMI). This study also indicated that the GGE biplot method was more effective than the AMMI method in analyzing genotype by environment and identifying superior genotypes. Overall, G6 can be introduced as the superior-most genotype for cultivation in Iran’s warm-temperate regions.

伊朗暖温带地区高粱苗种的GGE双图与AMMI分析

摘要由于干旱和半干旱地区农民越来越重视高粱种植，因此有必要引进新的、合适的高粱品种。本研究旨在通过AMMI和GGE双标分析评估粮食高粱基因型的产量稳定性，以确定伊朗暖温带地区高产和最适合释放的基因型。在2019年和2020年的生长季节，在伊朗的七个地区（卡拉吉、伊斯法罕、戈尔根、比尔詹德、设拉子、扎波尔和哈梅丹）研究了七个有前景的谷物高粱品系（KGS15、KGS19、KGS23、KGS25、KGS27、KGS32和KGS36）以及三个商业品种（Kimiya、Payam和Sepideh）。AMMI分析显示基因型G7、G3和G6具有最低的AMMI稳定性值（ASV）。GGE双位点分析表明，基因型G6在大多数环境中具有最高的粮食产量（GY），而基因型G1特别适合哈梅丹省。根据GGE双位点的平均环境协调性，基因型G6是最理想的基因型，显著优于第二和第三好的基因型G4和G3（AMMI遗漏了G4）。本研究还表明，在逐环境分析基因型和鉴定优良基因型方面，GGE双标法比AMMI法更有效。总的来说，G6可以作为在伊朗暖温带地区栽培的最优越的基因型引入。
