Effective adoption of the Pinto Saltillo common bean variety (Phaseolus vulgaris L.) in Durango and other states of México.

Resumen

Objective: To analyze the area of effective adoption of the improved common bean variety (Phaseolus vulgaris var. Pinto Saltillo) in México.

Design/Methodology/Approach: The area planted with Pinto Saltillo was obtained from the Statistical Yearbook of Agricultural Production (SIAP) and other data sources. Variables such as planted area, seed yield, and total production under both rainfed and irrigated conditions were included. The data were analyzed using principal component analysis (PCA), descriptive statistics, graphs, trend lines, and maps showing the level of technological adoption.

Results: The results show a gradual reduction in the annual area planted with common bean in the state of Durango (39-97%). Extensive Pinto Saltillo plantings were observed in 11 states in México, mainly under rainfed conditions. The highest cumulative values were recorded in Durango. The state of Zacatecas ranked first due to its high Pinto Saltillo planting area under irrigation (47,838 ha year⁻¹), followed by Chihuahua (30,840 ha year⁻¹). In México, the cumulative area planted with Pinto Saltillo between 2012 and 2024 reached 5.1 million hectares, with a total grain production of 2.8 million tons. Traits associated with the extensive adoption of Pinto Saltillo include disease resistance, high seed yield, slow seed coat darkening, and grain reduced cooking time.

Study Limitations/Implications: The study was conducted using information obtained from two databases; therefore, additional state, national, and international information sources should be considered in future analyses.

Findings/Conclusions: The productive and quality impact of Pinto Saltillo is evident on the common bean market, where the “Pinto Saltillo” commercial class has been recently introduced.
