Title : Environmental and morpho agronomic variability of Faba bean cultivation in Mexico
Abstract:
The broad bean (Vicia faba L.) in Mexico is cultivated in “Valles Altos”. With the objective of determining the morpho-agronomic variation of local populations, 60 accessions were collected that were identified with the meteorological data of the collection site (31 localities).” Results are described such as: viability in fertility, size and shape of pollen grain; the protein, lysine and tannin content; stomatal density, leaf area and root volume. The protein percentage varied from 17.9 to 33.0% and the lysine content was greater than 1.53%. Regarding stomatal variability (density, size, distance and area of the occlusive cells) there were significant differences in the number and distance between them. The morphological variability found is acceptable. Broad beans with seed lengths between 20 and 30 mm predominate. Bean seeds with a high percentage of protein provide more lysine than those with low content, there was wide variability in the tannin content in the testa and there was variability in the root volume in strata.
