Plant breeding programs seek to obtain genotypes with high yield, yield stability, and wide adaptability to environments. Selection of strains (genotypes) for adoption as crop inoculants has a similar aim. However, in both cases, the genotype × environment interaction hinders selection of materials adapted to the most diverse edaphic and climatic conditions. Nevertheless, with adequate biometric techniques, the variation in the response of each strain in the environments can be analyzed, allowing selection of those with the type of response and standard desired. In the present pioneering field study, the Toler and additive main effects and multiplicative interaction analysis models and the Annicchiarico method were used in a complementary manner with strains of nitrogen‐fixing bacteria that are symbionts with cowpea to determine their adaptabilities and phenotypic stabilities. The adaptability and phenotypic stabilities of strains INPA 03‐11B and UFLA 03‐164 were confirmed by these techniques. These strains have the most stable behavior regardless of the environment. The reliability of adopting these strains exceeded 85%. The good response of strain UFLA03‐164, still in the selection phase, is surprising, with results equivalent to application of mineral N, allowing it to be included among the strains approved as inoculants for cowpea.

利用生物特征识别技术筛选Bra豆根瘤菌的优良菌株

植物育种计划寻求获得具有高产量，高产量稳定性和对环境的广泛适应性的基因型。选择用作作物接种剂的菌株（基因型）具有相似的目的。然而，在两种情况下，基因型×环境的相互作用都阻碍了对适应最多样化的气候和气候条件的材料的选择。然而，使用适当的生物测定技术，可以分析环境中每种菌株的响应变化，从而可以选择具有响应类型和所需标准的菌株。在目前的开拓性野外研究中，耐性和加性主效应，乘性相互作用分析模型和Annicchiarico方法与are豆共生的固氮细菌菌株互补使用，以确定其适应性和表型稳定性。这些技术证实了INPA 03-11B和UFLA 03-164菌株的适应性和表型稳定性。无论环境如何，这些菌株都具有最稳定的行为。采用这些菌株的可靠性超过了85％。仍处于选择阶段的菌株UFLA03-164的良好响应令人惊讶，其结果与施用矿质N相当，这使其被包括在被批准用作as豆接种剂的菌株中。这些技术证实了INPA 03-11B和UFLA 03-164菌株的适应性和表型稳定性。无论环境如何，这些菌株都具有最稳定的行为。采用这些菌株的可靠性超过了85％。仍处于选择阶段的菌株UFLA03-164的良好响应令人惊讶，其结果与施用矿物质N相当，这使其被包括在被批准为cow豆接种剂的菌株中。这些技术证实了INPA 03-11B和UFLA 03-164菌株的适应性和表型稳定性。无论环境如何，这些菌株都具有最稳定的行为。采用这些菌株的可靠性超过了85％。仍处于选择阶段的菌株UFLA03-164的良好响应令人惊讶，其结果与施用矿质N相当，这使其被包括在被批准用作as豆接种剂的菌株中。
