Adaptability of yellow lupine varieties from the collection nurser

Breeding of general-purpose yellow lupine with stable yield potential in light-textured soils has undergone significant changes over the past four years due to the wide fluctuations in climatic conditions during individual phases of the growing season. Selecting parental forms for crossbreeding plays a key role in creating hybrid specimens with genotype dominance over changing environmental factors. According to a four-year analysis of grain yield data for 23 lupine varieties used in hybridization, the varieties Antey, Novozybkovsky 100, and samples 13-10-96 and 5-14-4 turned out to have a very high degree of adaptability to changing climate conditions; seven had a high degree of adaptability: the varieties Druzhny 165, Mister, and the 2010 and 2014 crossbreeding samples; and five had a medium degree of adaptability: the varieties Nadezhny, Rodnik, and the 2005, 2008, and 2012 crossbreeding samples. These varieties and samples are the basis for the best parental forms for continuing breeding research.
