METHOD OF ASSESSMENT OF ADAPTABILITY OF WINTER SOFT WHEAT PLANTS UNDER CONDITIONS OF SLOPE MICROZONALITY Russian patent published in 2015 - IPC A01H1/04 

FIELD: agriculture.

SUBSTANCE: invention is a method of assessment of adaptability of winter soft wheat plants under conditions of slope microzonality, comprising measuring and calculating an average value of height of winter soft wheat plants, the surface area of the flag leaf, the surface area of the second leaf and the weight of dry matter, the calculation of coefficient of adaptability to the conditions of growth of winter soft wheat plants according to the formula: k_a=Δx×K×0.1, where k_a is the coefficient of adaptability, Δx is average size of morphometric parameter, 0.1 is a constant component, K is the coefficient of proportionality (for the southern slope K=0+40, for the northern K=-0.35; for the western K=0.08; for the eastern K=-0.07), and the calculation of the overall coefficient of adaptability by the formula: k_{a tot}=(k_a1+k_a2+k_a3+k_a4)/4×0.1, where k_{a tot} is the total factor of adaptability, k_a1 is the coefficient of adaptability of the first morphometric parameter, k_a2 is the coefficient of adaptability of the second morphometric parameter, k_a3 is the coefficient of adaptability of the third morphometric parameter, k_a4 is the coefficient of adaptability of the fourth morphometric parameter, 4 is the number of morphometric parameters, 0.1 is a constant component, and those varieties of winter soft are determined as sustained, which have k_{a tot} more than 1.0; 0.7-1.0 are mid-sustained; less than 0.7 are low-sustained, where measurement and calculation of the average value of the height of winter soft wheat plants, area of leaf surface and weight of dry matter is produced on placor in the micro-zone of slope with the steepness of 1-3°and micro-zone of the slope with the steepness of 3-5°.

EFFECT: invention enables to assess the adaptability of winter soft wheat plants under conditions on the slope microzonality on morphometric parameters.
