چکیده
Identifying canola genotypes with high oil percentages and stability across diverse environmental conditions is crucial for breeding programs aiming to enhance crop productivity. Drought stress poses a significant challenge to canola yield, making the selection of adaptable genotypes imperative. This study investigates genotype-environment interaction (GEI) to identify stable canola genotypes with consistent oil percentages under varying conditions. Field experiments over two years in irrigated and rainfed environments evaluated fourteen genotypes using a randomized complete block design. Analysis of variance (ANOVA) revealed significant GEI effects, prompting a search for stable genotypes using stability analysis methods such as AMMI (Additive Main Effects and Multiplicative Interaction) and GGE (Genotype and Genotype by Environment Interaction) biplots. Results highlight Licord as the most stable genotype, maintaining consistent oil percentage across environments. Genotypes ۱۲, ۱۴, and ۵ exhibit minimal interaction, indicating stability, while genotypes ۵, ۷, ۸, and ۹ are more influenced by environmental factors, emphasizing the need for targeted breeding strategies.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
