THE CHANGE OF ARCHITECTONICS OF AN EAR AS A FACTOR OF INCREASING THE PRODUCTIVITY OF WINTER RYE

Abstract

The change of architectonics o f plants helps to optimize an optical-crop biological structure and to form the new morphological features of plants designed to increase the yield o f crops.The changes o f architectonics o f an ear plant of winter rye to improve a performance o f culture are grounded theoretically.It is proved that polystaching is one of the possible ways to improve plant productivity. Ramification of a rod ear makes it possible to increase the number of ears in the inflorescence and flowers and seeds according to the plant.The results of monitoring of cultural plant populations o f winter rye resulting in isolated samples of the branched structure o f the ear are shown. Polystachyres form received in the creation of candidates for sterility fixers of rye varieties through a hybridization with domestic and foreign lines o f hybrids. The selected sample 19-5 is analyzed by the major phenotypic characteristics.The studies found that an isolated polystachyres form has several agronomic traits, the main o f which is higher than the grade-standard offering.Sample 19-5 should be used in breeding research as a donor of polystaching, short-stemming, increasing the length o f the ear, number of grains in the ear and ear weight and grain, respectively, from the plant.
