FIERROS LEYVA, Gustavo Adolfo et al. Genotype-environment interaction in extra-large white chickpea seed in northwestern Mexico. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.3, pp.507-519. ISSN 2007-0934.

In Mexico white chickpea (Cicer arietinum L.) grain export large planted in the states of Sonora, Sinaloa and Baja California Sur. In 90% of the sowing area Blanco Sinaloa 92 variety, which has been sown for over 20 years it is used. The aim was to analyze the genotype-environment interaction (IGA) of16 advanced lines and two commercial varieties, and identify locations of low IGA, and lines of higher yield and grain weight (number of grains in 30 g). The 18 genotypes were established during the autumn-winter 2011-2012 under irrigation or temporary (residual moisture) in a randomized complete design in seven environments in Sonora, Sinaloa and Baja California Sur blocks. The IGA analysis was performed using the AMMI model. Yield and grain weight significant differences between environments, genotypes and genotype-environment interaction (p< 0.05) were detected. Environments greater performance were Santo Domingo, BCS with 3.63 t ha-1 under a system ofdrip irrigation and in Navojoa, Sonora, under traditional irrigation with 2.91 tha-1,with significant difference between them and the rest of environments. The highest average yield genotypes were Hoga 02 febrero, 2001 with 2.72 tha-1 and Hoga 06 marzo, 2002 with 2.60 t ha-1, only the first was significantly higher (p< 0.05) witnesses Blanco Sinaloa 92 and Blanoro. By weight of the grain, Culiacan, Sinaloa, Hermosillo, Sonora, and La Angostura, Sinaloa, localities were larger with 41, 47 and 47 grains in 30 g, respectively. The Hermosillo environment was the farthest from the origin, with greater capacity for discrimination, while Culiacan, Navojoa and Santo Domingo were the least interaction and represent environments where you can select stable varieties.
