PID 2: improved pinto bean variety with high yield and extended shelf life

Resumen

Objective: The bean production system in the state of Durango requires the development of an improved variety for irrigated and sufficient rainfed conditions (> 450 mm of rainfall). Design/Methodology/Approach: In accordance with the procedure for developing new varieties, the improved variety PID 2 (PT14053) was obtained via the pedigree method, using hybridization between ‘Pinto Saltillo’ and multiple progenitors, resulting in the genealogical key: PT Bayacora/Maverick///PT Claro/PT Saltillo//PT Saltillo/PT Villa‑2‑6. Results: The variety PID 2 consists of climbing‑habit plants with a height of 43 cm and an average vine growth rate of 93 cm. Pods are green with red coloration; seeds are broad, elliptic‑medium shaped, with a cream‑white testa, brown mottling, and yellow hilum. Under irrigation it achieved an average yield of 2,783 kg ha⁻¹, with flowering at 47 days after sowing (DAS), intermediate maturity at 104 DAS, and a 100‑seed weight of 36 g. Findings: The experimental line PT14053, commercially registered as PID 2, was developed for irrigated conditions in the state of Durango. It features disease resistance, acceptable yield (> 1,640 kg ha⁻¹), testa clarity, extended shelf‑life, and seed weight exceeding 35 g per 100 seeds.
