Genetic determination of high productivity in experimental hybrid combinations of sugar beet (Beta vulgaris L.)
Journal Title: Plant varieties studying and protection - Year 2016, Vol 0, Issue 2
Abstract
Purpose. Creation of experimental sugar beet hybrid combinations of high sugar yield values and defining genetic determination of their heterotic effect. Methods. Diallel crossing and topcrossing, genetic analysis of quantitative traits. Results. The authors have studied the frequency of occurrence of sugar beet heterotic hybrid combinations for «sugar yield» trait created on the basis of two pollinator lines to be genetically valuable for productivity elements, CMS lines and single-cross sterile hybrids with the use of diallel and topcrossing system of controlled hybridization. The share of parental components’ effect and their interaction in CMS hybrids variability for productivity was determined. Expediency of heterotic forecasting based on high combining ability lines was substabtiated. Promising high-yielding sugar beet combinations were selected that exceeded the group standard by 4.1–16.3%. Conclusions. The theory of genetic balance by M. V. Turbin was confirmed. Such hybrids as [CMS 5OT 4]MGP 1 (116.3%), [CMS 1OT 2]MGP 1 (112.5%) and [CMS 3OT 5]MGP 1 (113.2%) were recognized as the best for their productivity, MGP 1 and MGP 2 lines – as the best for their combining ability.
