New power-saving complex for drying seeds of corn

Abstract

The purpose. To determine efficiency of induction of mutations of oil flux by means of new chemical mutagens, derivatives of dimethyl sulphate — DG2, DG-6, DG-7, DG-9, to establish directedness of their action in comparison with initial substance and to create on this basis of new initial stock for selection. Methods. Field, laboratory, mathematical-statistical. Results. It is established that owing to treatment of seeds of flux of two varieties by new chemical mutagens DG-2, DG-6, DG-7, and DG-9 in densities of 0,5 and 0,05 % the wide spectrum of mutations (29 types) is gained in generation M2. They were divided into 6 groups: 4 groups with changes of morphological type, one group with changes of physiological type, and one — with biochemical type. As a result the collection is gained of mutant samples which are donors of marker and economic-valuable attributes, and also different on biochemical contents of oil. Conclusions. For induction of mutations with breaking synthesis of chlorophyll pigment the most effective was mutagen DG-9, for mutations of structure of stalk, shoots and leaves — mutagens DG-7 (for variety Iceberg) and DG-6 (for variety Solnechnyi), for mutations of flower — DG-2, and also DG-9 (for variety Iceberg) and DG-7 (for variety Solnechnyi), for mutations of colour of seeds at variety Iceberg — mutagens DG-2 and DG-9, at variety Solnechnyi — mutagens DG-2 and DG-7, and for mutations to physiological attributes of growth and development — mutagen DG-2. The most effective at change of biochemical indexes of oil in seeds was mutagen DG-2.
