THE INFLUENCE OF THE TYPE PANICLES ON ECONOMIC VALUABLE TRAITS OF MILLET

Surkov, A.Yu. | Surkova, I.V.
The article presents the results of the competitive variety testing of millet varieties studied in 2015-2017, as well as the rank correlation analysis of the relationships between the type of panicles and the economic-valuable traits of millet in varieties of ecological, preliminary and competitive variety testing (2011-2017 years). It was revealed that in the conditions of the south-east of the Central Chernozem Region, varieties with a compressed type of panicle are characterized by a specific adaptive ability, reflecting the total reaction of the genotype in the totality of the media, have low stability, which significantly reduces their breeding value. Varieties with a branching type of panicle combine high yields with relative stability, which dramatically increases their breeding value. The branching forms of millet had a higher grain yield and protein content than compressed, especially in wet years. The compressed forms of millet were distinguished by high productivity of panicle, a large grain with high content of carotenoids and brightness of the nucleus. Evaluation of millet samples for resistance to melanosis showed that specimens with a compressed type of panicle in conditions of excessive moistening were more affected by the disease than samples with a branching type of panicle. The specimens with a branching type of panicle dried out faster, thereby reducing the damage to melanosis. These features should be taken into account in selection work when creating new varieties adapted to the conditions of the Voronezh region and the Central Black Earth region
