Studies on stability of grains number from panicle to a collection of oats autumn (Avena sativa L.) genotypes
Journal on Processing and Energy in Agriculture(2022)
摘要
The study aimed at assessing stability the grains number from panicle to autumn oats, under the influence of climatic conditions. The study was conducted over a period of three years. The biological material consisted of 73 genotypes. The experimental data was obtained by performing biometric measurements. The experimental data was processed by various linear regression analysis modelesses: Finlay-Wilkinson, Hardwick-Wood, Muir, Wrike but also the concordance between the ranks of different models of appreciation. The values of grains number in panicle fluctuate according to the climatic conditions of the year, both as an average value and as intrapopulational variability. The Jeferson, Carie, Florina varieties, and the 4458, PA 725-4743, PA 822-818 lines exhibits a high dynamic stability associated with values above the average of the experience for the number of grains in panicle. In the case of this character, 53.10% of the genotype x environment interaction is due to heterogeneity of variances.
