Effect of lithuanian genotypes resistance to anthracnose (Colletotrichum spp.) in Lupinus angustifolius L.

Abstract

Breeding for disease resistance is one of the most difficult tasks in breeding work. Rapid mutation of pathogen’s populations, its ability to continuously form a large amount of races differing in virulence and aggressiveness are the chief obstacles in the development of disease-resistant lupine varieties. Of 2019—2021 year twelve narrow-leafed forage lupine genotypes developed by the individual selection methods and characterised by a high resistance to anthracnose (Colletotrichtum gloesporoides (Penz.) Penz & Sass.) resistance 7—9 points, rapid growth rate, and a high seed yield 1.3—3.8 t/ha were tested at the competitive variety testing trials. The investigated lines are a valuable material from the viewpoint of genetics, breeding and agronomic characteristics which will be used in subsequent breeding work and the most promising lines will be transferred to the official variety testing.
