INVESTIGATION ON MORPHOLOGICAL TRAITS ON LEAF, POD AND SEED OF LOCAL BEAN (Phaseolus vulgaris L.) POPULATIONS IN MACEDONIA

Abstract

In this research there were analyzed forty-four (44) local bean populations from ssp.nanus (dwarf), sown on open field in randomized complete block design during 2008 at Institute of Agriculture, Skopje. Tested varieties were compared with two Slovenian varieties used as check variety. The objective was to identify some morphological parameters on leaf, pod and seed of these bean populations. The whole examined material was collected from eastern part of Macedonia from Malesregion, precisely from Pehchevo. Characterization and the determination of genetic variability were described according to the list of descriptors for beans of the International Commission on Genetic Resources– IBPGR (International Board for Plant Genetic Resources). Generally, all tested varieties showed differences in terms of the examined traits. Approximately half of the analyzed populations had a green leaf with a triangular shape and rare fibrous. The average values for length/ width of leaf range from 7.02-11.17cm and 4.59-8.16cm. The length and width traits of the leaf showed relatively low variability from 12.72% to 13%. In the analyzed collection the most of the landraces had a green color of pod, curved legumes, with round-oval and pear-shaped cross-section.&nbsp
