JIMENEZ-HERNANDEZ, Yanet; ACOSTA-GALLEGOS, Jorge Alberto; SANCHEZ-GARCIA, Bertha María  y  MARTINEZ GAMINO, Miguel Ángel. Agronomic traits and Fe and Zn content in the grain of common Rosa de Castilla type bean (Phaseolus vulgaris L.). Rev. Mex. Cienc. Agríc [online]. 2012, vol.3, n.2, pp.311-325. ISSN 2007-0934.

The 'Rosa de Castilla' type bean is popular in areas of Guanajuato, San Luis Potosí and Zacatecas, where it is produced under rainfed conditions. The aim of this research was to compare the agronomic characteristics of 22 RC accessions with two bred cultivars of the Flor de Mayo type beans grown under rainfed conditions. The trial was established during 2008 under rainfall conditions in two locations in the state of Guanajuato: Celaya (1 785 masl) and Ocampo (2 200 masl), as well as one in San Luis Potosí, in Villa de Arriaga (2 200 masl). A complete random block design was used. At the locations in Guanajuato, phenological characteristics and reactions to diseases were established, and in all three locations, seed yield and the weight of 100 seeds were determined; also, the iron and zinc contents were established in one seed sample for each material. Significant differences (p< 0.01) were observed for seed yield, weight of 100 seeds, and iron and zinc seed content for the effects of location, genotype and the interaction of both. Throughout locations, the greatest yield, > 1 3 00 kg ha-¹ was obtained by accessions RCG08001, RCA06001 and RCZ06001. The highest weight for 100 seeds was found in RCSLP 08001, with 40.2 g. For mineral content, outstanding accessions were RCG 08011 and RCZ06001 with > 65 and 40 ppm for Fe and Zn, respectively. In comparison to the checks, accessions displayed a long growth cycle and susceptibility to rust and halo blight.
