ENVIRONMENTAL PLASTICITY OF GREEN BEANS IN THE FOREST-STEPPE OF THE NOVOSIBIRSK OB REGION

Abstract

The article estimates the environmental plasticity of green beans varieties (Phaseolus vulgaris L.) of different ecological and geographical origin. The research was carried out at the experimental field of Novosibirsk State Agrarian University “Sad michurintsev” in 2014-2015. The experimental plot is located on the right bank of Novosibirsk (the river Ob) in the forest-steppe of the Ob basin where the soil of the plot is grey forest heavy loamy on the leached heavy loam. The object of research was 9 sorts of green beans; the researchers investigated the varieties according to the main elements of productivity: the amount of beans on the plant 9 (pcs), the mass of beans pro a plant (g), the mass of 1 bean (g) and crop yield (kg/m2. The authors calculated the parameters of environmental plasticity according to the methodics of S.A. Eberhart and W.A. Russell rendered by Zykin V.A. The authors calculated the coefficient of regression, highlighted the sorts with different environmental plasticity and divided collection green beans sorts into 2 groups: the neutral sorts with low environmental plasticity and the intensive sorts with high environmental plasticity. The neutral sorts are considered as resistant to the changes of environmental factors in spite of their slight response to growing conditions. The intensive sorts in environments with agricultural equipment and favorable hydrothermal conditions differ in their response and their productive elements grow. The paper outlines Yubileynaya and Viola sorts as they are referred to the intensive ones with high environmental plasticity according to all 4 elements; Sekunda and Nika sorts are referred to the intensive sorts according to 3 productive elements and Rocquentcant sort is referred to the intensive types according to 2 productive elements. The authors recommend to include the neutral and intensive sorts into selective genetic programmes as sources of stable response to the changes in cultivation. The intensive sorts should be used for sowing at the farms and in industry as the most productive ones.
