Einkorn Wheat Tillering: Models of Inheritance

Abstract

The need for einkorn wheat breeding improvement is due to its value as a source of healthy nutrition. Tillering is an important agronomic trait determining yield. Genetic analysis of tillering was carried out on reciprocal hybrids between accessions of T. monococcum L.: var. nigricultum (UA0300311) and var. monococcum (UA0300282). It was found that the segregation pattern on this trait depends on vegetation conditions. Segregation in the F2 of reciprocal crosses indicates effect of two major genes with a series of polygenes which influence the quantitative expression of tillering with different efficiency degrees. The heritability of tillering in reciprocal crosses is of 68-71 % and 84-92 %.
