coccineus Cultivars]]>GutierrezM. Escalante-EstradaJ. A.Rodriguez-GonzalezM. T.9200949Diverse cultivars of Phaseolus vulgaris L. and Phaseolus coccineus L. were tested under saline conditions to evaluate yield performance and to estimate physiological differences (chlorophyll, stomatal conductance and transpiration rate). The study was carried out in Central Mexico in a low saline soil (pH 6.8-7.5 and EC of 2-5 dS m-1) and high saline soil (pH 8-8.7 and EC of 5-8 dS m-1). Three P. vulgaris cultivars and one P. coccineus cultivar were planted in a high saline soil during 2003, while thirteen P. vulgaris cultivars and three P. coccineus cultivars were planted in a low saline soil during 2004. The experimental design for both saline fields was a randomized complete block with four replicates. The P. vulgaris cv. Bayomex showed the highest seed yield, biomass and pod number under high saline conditions, while the P. coccineus cv. Ayocote Negro showed a lower seed yield and biomass, but higher seed weight. Canario-107 and Criollo were the P. vulgaris cultivars with the lowest yield during 2003. For the season 2004 under low saline conditions, four P. vulgaris cultivars (Zacatecas, Ojo de Cabra, Morito and Bayo-18) showed higher seed yield, biomass and seed weight, but the three P. coccineus cultivars showed major yield in all parameters. Generally, the cultivars of both crop species with high yield presented high chlorophyll levels than the sensitive cultivars under low and high saline conditions. In low salinity, the P. coccineus and P. vulgaris cultivars showed diversity in leaf stomatal conductance, transpiration rate and leaf temperature. Stomatal conductance explained yield differences among cultivars of both crop species showing two well defined groups (one for each crop species).]]>Adiku, S.G.K., M. Renger, G. Wessolek, M.
