Variation in plant responses to inoculation with rhizobia strains in different environments can be analyzed with the aid of biometric techniques. The Annicchiarico methodology and the Additive Main Effects and Multiplicative Interaction Analysis (AMMI) and Toler models are here applied to the genotype × environment (GE) interaction to determine the adaptability and phenotypic stability of N2-fixing bacteria in symbiosis with common bean (Phaseolus vulgaris L.) in environments with high, moderate, and low acidity and with deficiencies or excessive concentrations of nutrients. A randomized block design was used in eight environments, with four replications and seven bacterial genotypes, including two controls with native soil bacterial communities (with or addition without mineral-N fertilization). Individual and combined analyses of variance and biometric analyses were conducted on the yield values. CIAT899, UFLA02-127, and native rhizobia were the most stable genotypes in relation to environments (AMMI models). CIAT899 and native rhizobia are the least adapted (Toler models), whereas the genotype UFLA02-127 has the best response to the environments (Toler models). The Annicchiarico method showed that the reliability of adoption of UFLA02-127 and native rhizobia fertilized with mineral N exceeds 85%, indicating high probability of increase in common bean yield if adopted in the field. Conversely, native rhizobia have <65% reliability.

生物特征技术筛选根瘤菌优良菌株接种普通豆类

可以借助生物识别技术分析植物在不同环境中接种根瘤菌菌株的反应变化。Annicchiarico 方法和加性主效应和乘法相互作用分析 (AMMI) 和 Toler 模型在此应用于基因型 × 环境 (GE) 相互作用,以确定与普通豆 ( Phaseolus)共生的 N 2固定细菌的适应性和表型稳定性寻常的L.) 在高、中、低酸度以及营养缺乏或浓度过高的环境中。在八个环境中使用了随机区组设计,具有四个重复和七个细菌基因型,包括两个具有天然土壤细菌群落的对照(添加或不添加矿物氮肥)。对产量值进行了方差分析和生物统计分析的单独和组合分析。CIAT899、UFLA02-127 和天然根瘤菌是与环境相关的最稳定的基因型(AMMI 模型)。CIAT899 和天然根瘤菌最不适应(Toler 模型),而基因型 UFLA02-127 对环境的响应最好(Toler 模型)。Annicchiarico 方法表明,采用 UFLA02-127 和天然根瘤菌以矿物 N 施肥的可靠性超过 85%,如果在田间采用,表明普通豆产量增加的可能性很高。相反,原生根瘤菌的可靠性<65%。
