Abstract
AbstractThe objective of this study was to assess genotype by environment interaction for seed yield in rapeseed cultivars grown in West Poland by the additive main effects and multiplicative interaction model. The study comprised 25 rapeseed genotypes (15 F1 CMS ogura hybrids, their parental lines and two varieties: Californium and Hercules F1), analyzed in five localities through field trials arranged in a randomized complete block design, with four replicates. Seed yield of the tested genotypes varied from 15.9 to 80.99 dt/ha throughout the five environments/localities, with an average of 39.69 dt/ha. In the variance analysis, 69.82 % of the total yield variation was explained by environment, 13.67 % by differences between genotypes, and 8.15 % by genotype by environment interaction. Seed yield is highly influenced by environmental factors. Due to high influence of the environment on yield high adaptability of the genome is required.
