Název v původním jazyce

Study of prezygotic and postzygotic barriers of crossability in the genus Lotus.

Popis výsledku v původním jazyce

Lotus corniculatus L. is a crucial component of meadow and pasture vegetation and can be used as a fodder crop. Its growth is limited by differences in maturation and pod shattering, which also affect the seed yield. Shattering resistance is a characteristic of high heritability and, in Lotus, is considered to be controlled by more than one gene. Classical breeding approaches to reduce shattering through recurrent selection were unsuccessful. The problem of pod shattering can be solved by means of interspecific hybridization with various distantly related indehiscent Lotus species. Our work was aimed at the study of prezygotic and postzygotic barriers of crossability between L. corniculatus and sources of the indehiscent seed pod trait, such as L. uliginosus (2n=2x and 4x). The growth of the pollen tubes up to the ovary was observed after the crosses of L. corniculatus x L. uliginosus (2n=2x and 4x). This means that prezygotic barriers were not detected in this combination. In L. corni
