Working collection of lupine gene pool as effective tool for use in breeding programs

Abstract

Aim. To study collection accessions of the lupine gene pool for valuable economic characteristics and to build up a working collection from sources selected for the conditions of the Ukrainian Woodlands in accordance with current trends in this crop breeding. Results and Discussion. 150 accessions of the yellow lupine (L. luteus L.), 95 accessions of the white lupine (L. albus L.) and 40 accessions of the narrow-leaved lupine (L. angustifolius L.) of different eco-geographic origins from the collection of the Institute of Agricultural Microbiology and Agricultural Production of NAAS were investigated. The three-year results on 285 accessions of the lupine gene pool studied in the conditions of the Left-Bank Woodlands of Ukraine are presented. The selected sources of economically valuable traits became the basis of the lupine working collection, where traits were picked out for the regional conditions and in accordance with the current trends in this crop breeding. The collection includes 95 accessions of the yellow, white and narrow-leaved lupine species with varying expression of 11 economically valuable traits and is recommended as a genetic basis and valuable starting material for creating new, highly productive, early maturing varieties of fodder lupine. Conclusions. We built up the working collection of the lupine gene pool. There was a correlation between the performance elements (seed weight per plant, pod and seed numbers per plant) and the total yield of seeds per unit area (r = 0.520 – 0.957).
