It’s common knowledge that any success of breeding work largely depends on initial material. The staff of Krasnodar RIA named after P.P. Lukiyanenko is carrying out a significant work in breeding, assessment and classification of new initial material for breeding of maize hybrids with high heterosis...

With the application of hybrid wheat, lodging is becoming one of the major factors limiting high yield in its production. However, few studies have focused on combining ability and heterosis analysis of stem-related traits. In this study, 24 crosses were made according to NCII genetic design, using...

For the successful development of competitive sunflower hybrids, it is necessary to have a sufficient number of parental lines with valuable breeding traits and high combining ability. In the zone of insufficient moisture of the Rostov region, there were studied the plants to determine the general (...

The article presents the results of research work on the assessment of general combining ability (GCA) and specific combining ability (SCA) in 14 varieties of meadow clover (Trifolium pratense L.) of various ecological and geographical origin (Russia, Belarus). The study was aimed at identifying the...

Hybrid maize breeding is carried out based on interline hybridization using heterosis in the first generation. Hybridization efficiency can be increased using parental forms with high combining ability in crosses. The purpose of the study was to identify new self-pollinated lines of maize with high...

Relevance. The creation of heterotic hybrids of watermelon is one of the modern breeding trends for solving the problem of providing the population of the Russian Federation with melon production. The process of creating heterosis hybrids can be accelerated by the assessment of the total combination...

Vitamin A deficiency has become a worldwide problem. Biofortified foods can potentially be an inexpensive, locally adaptable, and long-term solution to dietary-nutrient deficiency. In order to improve the β-carotene content in maize grain by breeding and minimize vitamin A deficiency, a complete dia...

Relevance. The selection for productivity and stability on different stages in the breeding process includes an assessment of the adaptive capacity and genotypes ecological stability. Therefore breeding for the resistance to abiotic environmental factors is closely connected with the adaptive breedi...

Genetic potential of productivity is a primary and essential factor in the period of formation of high productivity of winter wheat. Such quantitative traits as 1000-grain weight, a number of seeds per ear, length and width of a flag leaf are of primary importance while forming productivity of the c...

Relevance. To create heterotic cucumber hybrids, it is important to have a high general and specific combining ability of the initial material, which makes it possible to select valuable genotypes at an early stage of selection. Material and methods. The research was carried out in 2018-2020. at the...

Abstract: General combining abilities (GCAs) are very important in utilization of heterosis in maize breeding. However, its genetic basis is unclear. In the present study, a set of 118 doubled haploid (DH) lines were induced from F1 generations produced from the cross between the inbred line Zheng 5...

The present study was to determine the nature of gene action and combining ability of six quantitative traits related to productivity of five varieties and ten hybrid combinations of durum wheat. Five modern durum wheat varieties were used in diallel crosses as parents. The study includes three F1 a...

In the present study, effects of crossbreeding on egg production traits were evaluated using a 4 × 4 full diallel cross involving four chicken breeds: Improved Horro (H), Sasso (S), Potchefstroom Koekoek (K), and Dz-white feathered (D). The experiment included 800 chickens in a completely randomized...
