Fenología de cultivares locales de frijol y arveja del municipio Rafael Urdaneta, estado Táchira, Venezuela, basada en grados día

the objective of the present study was to collect local cultivars of peas and common bean for morphological characterization and determination of their phenological cycle based on degree days (d.°c). the cultivars of edible the leguminous crops phaseolus vulgaris l. (common bean) and pisum sativum l. (peas) were collected in 47 farms at alto viento, aguaditas y betania villages (rafael urdaneta municipality, táchira state, venezuela). a greenhouse trial was established in palo gordo, cárdenas municipality, táchira, at 1.100 m.a.s.l. legumes were individually planted in 5 kg plastic bags with 40 replications per cultivar. nineteen characters including leaf, fl ower, fruit and production parameters were recorded according to ipgri？s recommedations. there was ample morphological variation for each character with substantial differences among cultivars in their phenometric and qualitative variables. the phenological cycle for common bean and peas required 796 to 888 oc and 845 to 951 d.oc, respectively, varying the requirements of thermal units according to cultivars and phenological phases
