Yielding and ecological plasticity of pea cultivars various morphotypes in different periods of varieties change

The results of the study of pea cultivars various morphotypes in different periods of varieties change. The estimation of the modern varieties of peas on grain yield and stability of its formation. It is shown that in the last 20 years varieties change grain yield of modern cultivars have a mustache and heterophile morphotype increased by 12 - 28%. Increased adaptability of new varieties to changing environmental conditions.
