The aim of this study was to evaluate the phenotypic stability and specific and broad adaptability of common black bean genotypes for the Central and Center-South regions of Brazil by using the Annicchiarico and AMMI (weighted average of absolute scores: WAAS, and weighted average of absolute scores and productivity: WAASP) methodologies. We carried out 69 trials, with 43 and 26 trials in the Central and Center-South regions, respectively. Thirteen genotypes were evaluated in a randomized block design with three replications, during the rainy, dry, and winter seasons in 2 years. To obtain estimates of specific adaptation, we analyzed the parameters for each method obtained in the two geographic regions separately. To estimate broad adaptation, we used the average of the parameters obtained from each region. The lines identified with high specific adaptation in each region were not the same based on the Annicchiarico and AMMI (WAAS) methodologies. It was not possible to identify the same genotypes with specific or broad stability by using these methods. By contrast, the Annicchiarico and AMMI (WAASP) methods presented very similar estimates of broad and specific adaptation. Based on these methods, the lines with more specific adaptation were CNFP 8000 and CNFP 7994, in the Central and Center-South regions, respectively, of which the CNFP 8000 line was more widely adapted.
本研究的目的是通过使用安尼恰里科方法以及AMMI方法(绝对得分加权平均值:WAAS,以及绝对得分和生产力加权平均值:WAASP),评估普通黑豆基因型在巴西中部和中南部地区的表型稳定性、特异性和广泛适应性。我们进行了69次试验,其中在中部地区进行了43次试验,并在中南部地区进行了26次试验。在两年的雨季、旱季和冬季,以随机区组设计对13个基因型进行评估,每个基因型有三次重复。为了获得特异性适应性的估计值,我们分别分析了在两个地理区域中每种方法得到的参数。为了估计广泛适应性,我们使用了从每个区域获得的参数的平均值。基于安尼恰里科方法和AMMI(WAAS)方法,在每个区域中确定的具有高特异性适应性的品系并不相同。使用这些方法无法鉴定出具有特异性或广泛稳定性的相同基因型。相比之下,安尼恰里科方法和AMMI(WAASP)方法在广泛和特异性适应性方面的估计值非常相似。基于这些方法,在中部和中南部地区,分别具有更高特异性适应性的品系是CNFP 8000和CNFP 7994,其中CNFP 8000品系具有更广泛的适应性。
