Possibilities for identification of the genotype by phenotype in white lupine ( Lupinus albus L. ) cultivars

摘要

The application of traditional analyses and methods in breeding-genetic researches is necessary to be combined with the study of the ecological-genetic model for organization of the quantitative trait revealing a new perspective in the plant breeding. The present study was conducted during the period 2015-2016 at the Institute of Forage Crops (Pleven) with 23 white lupine cultivars with different origin. The issue of breeding identification of the best white lupine cultivars from the available collection in their phenotype was examined. A rationale of the principle "background trait" was represented with purpose for effective breeding activity. Characteristic of the possibility of using the mean values of plant seed weight and crude protein content in seeds in the selection of parental forms for the needs of the combinative breeding was made.
