| Abstract : | In the years 2011-2012, thirteen cultivars and breeding lines of Chinese origin adzuki bean (Phaseolus angularis W.H. White) were evaluated for their selected breeding characters and seed protein content in the climatic conditions of Central Europe. In the field experiment, the evaluation included seedlings emergence, number of pods per plant, number of seeds per pod and plant health status. In the laboratory research, the assessments included seed germination as well as seed dry matter and total protein contents. In Western Poland climatic conditions, it was possible to produce seeds of adzuki bean. However, in cold and wet years, they did not set seeds. The tested materials differed in plant emergence, earliness, number of pods per plant, number of seeds per pod and plant health status. The produced seeds had germination capacity from 0 to 54% and no symptoms of bean weevil (Acanthoscelides obtectus Say) damage. They also had from 20.01 to 31.91% of total proteins in d. m., which proved they could be a valuable source of plant protein. Amongst the evaluated materials, one breeding line (marked with the letter J) turned out to be the best, whereas the other one (marked Z1) was also interesting for further breeding work. |
