Heterotic grouping of wheat hybrids based on general and specific combining ability from line × tester analysis.

ABSTRACT: The most important step in plant breeding is the correct selection of parents, and it would be wise to use heterotic groups for this. The purpose of this study is to analyse yield and its components as well as genetic diversity in line × tester wheat populations. It also seeks to present a coherent framework for the isolation of early superior families and the development of heterotic groups in bread wheat. F₁ and F₂ generations of 51 genotypes, including 36 combinations between 12 lines and three testers and 15 parents, were evaluated for yield and its components in a three-replication experiment according to the randomized block design. Line ×  tester analysis of variance, general and specific combining abilities, heterosis, heterobeltiosis and inbreeding depression
