Twenty one F2 progenies derived from a 7×7 diallel crosses along with parents were evaluated for grain yield, flowering and maturity time. Due to significant genotypic effects for all traits, genetic analyses were performed on F2 progenies including analyses of combining ability and genetic components. The Analysis of variance revealed that both additive and non-additive genetic effects were in...

1. Many Salicaceae species naturally form hybrid swarms with parental and hybrid taxa that differ in secondary chemical profile and in resistance to herbivores. Theoretically, the differential mortality in the seedling stage can lead to changes in trait expression and alter subsequent interactions between plants and herbivores. This study examines whether herbivory by the generalist slug Arion ...

Aim: specify the spike color inheritance in einkorn wheat (Triticum monococcum L.) hybrids. Methods: reciprocal hybrids between black-spikeed UA0300282 and white-spikeed UA0300311 cultivated accessions were created with use of “single cross” method. Four generations analyzed using segregation analysis method: P1, P2, F1, F2 at autumn spring sowing. Results: it was found that for combination × s...
