Relationships between agro/morphological characters and climatic parameters in Spanish landraces of lentil (Lens culinaris Medik.)
One hundred and one Spanish landraces of lentil maintained in the Plant Genetic Resources Centre (CRF) and coming from different micro-climatic areas were evaluated for 16 morphological characters. Origin zones were classified following Papadakis agro-climatic parameters and the relationships between climatic data zones and morphological traits were analysed. The results indicated that a great part of the landraces came from temperate areas with dy Mediterranean moisture regime. Most of the varieties had plant pigmentation, slight leaf pubescence, white flowers with blue or violet veins, green testa without pattern and yellow cotyledons. Two clear morphological groups based on seed characters could be established coinciding with Barulina's description for the macrosperma and microsperma types. Other traits of high agronomic importance as phenology and plant height showed less usefulness in discriminating accessions. Characters related to seed and productivity had most correlation with climate of the origin sites, while phenology and plant height did not show significant correlations. Thes climatic variables related with extreme temperatures were more effective than average temperatures or rainfall to explain the morphological variability. The agro-climatic patterns detected seems to be due to the geographical location of the two morphological lentil groups in zones with different climatic conditions, indicating that lentil landraces must be migrated following criteria related with seed characters preferred by farmers.
