METHOD TO SELECT HIGHLY PRODUCTIVE FORMS OF SOYA BEANS

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to the field of agriculture, namely, to selection. The method includes growing of individual plants in the field within a population and their rejection - selection by the ratio of SC/BC (selection criterion/background criterion) with account of the nature of ecological regression. At the same time the selection criterion is mass of plant seeds, and the background criterion is the value of the diameter of the lower internode of the main shoot of the plant in the phase of complete ripening. The value of the lower internode diameter of the main shoot of the plant is measured under field conditions with the help of vernier callipers. The mass of plant seeds is determined by tearing of fruitage from a plant in the field, subsequent threshing of fruitage and weighing of the produced seeds under laboratory conditions.;EFFECT: method makes it possible to reduce duration of background criterion accounting process, to increase accuracy of selection of highly productive forms of soya beans with simultaneous simplification of selection method, and also to expand the list of used background criteria.;3 cl, 1 tbl, 1 ex
