Zastosowanie modelu AMMI do analizy interakcji genotypowo-srodowiskowej masy tysiaca ziaren jeczmienia jarego

摘要

The objective of this study was to assess genotype by environment interaction of thousand-grain weight in spring barley grown in South-West Poland by using the AMMI model. The study comprised of 25 spring barley genotypes (five cultivars: Basza, Blask, Antek, Skarb and Rubinek as well as all possible 10 two-way mixtures and 10 three-way mixtures combinations), evaluated at eight locations (two locations in four years) in a randomized complete block design, with four replicates. Thousand-grain weightof the tested genotypes ranged from 39.55 g (for Antek/Rubinek in Baków 2011) to 53.25 g (for Skarb in Baków 2010), with an average of 45.60 g. In the AMMI analyses, 26.03% of the thousand-grain weight variation was explained by environment, 7.24% by differences between genotypes, and 14.48% by genotype by environment interaction. The cultivar Rubinek and mixtures Antek/Blask/Skarb and Antek/Rubinek/Skarb are recommended for further inclusion in the breeding program due to their high average thousand-grain weight and their high stability.
