Evaluation of Yellow and Angustifoliate Lupin Breeding Material for Anthracnose Resistance
The article presents the test results of yellow and angustifoliate lupin breeding material on anthracnose infectious background in 2011-2014. The breeding strategy for disease resistance has got a number of common principles based on biological properties of an agent, effect of selection intensity, resistance scales, environment effect and local specificity, resistance duration and type. The aim of the studies is to select perspective initial lines with high resistance, as well as sources of anthracnose resistance in order to develop new competitive varieties. The studies have been carried out in the field conditions on the specialized infectious background in the Russian Lupin Research Institute. The collection and breeding material of yellow and angustifoliate lupin have been tested there. The soils of the experimental plot are sandy loam grey forest. The natural population of anthracnose agent was used as the infectious material. The material has been collected in different lupin cultivation regions. Lupin breeding lines testing and evaluating was carried out in the period of 2011-2014. These years differed in climatic conditions as well as in infection intensity of the tested lupin species. It should be noticed that breeding lines have been evaluated under equal qualitative and quantitative infectious load of the pathogen introduced at the growth period typical of each lupin species (the most favorable for anthracnose development). The tests results in selection of three yellow lupin lines (2954, 5321, 9171) and 5 angustifoliate lupin ones (9673П, 9649, 9688П, 9714(3), 10289). Under moderate epiphytotic anthracnose development their stem and legume’ infection level was significantly lower as compared to the standard varieties as well as to the other test lines.
