Abstract
Resistance to stem canker (Leptosphaeria spp.) in interspecific Brassica hybrids
Highlights
The incorporation of Leptosphaeria resistance into Brassica lines with desirable agronomic and quality traits is a major concern in breeding programs
The aim of this study was to identify the sources of genetic resistance to stem canker in Brassica hybrids obtained from the crossings between two high yielding cultivars (Jet Neuf and Californium) of B. napus and B. carinata, B. fruticulosa, B. rapa ssp. chinensis and B. rapa ssp. pekinensis
Between parental species the lowest percentage of infected plants were observed on the B. napus variety Jet Neuf and on B. carinata
Summary
The aim of this study was to identify the sources of genetic resistance to stem canker in Brassica hybrids obtained from the crossings between two high yielding cultivars (Jet Neuf and Californium) of B. napus and B. carinata, B. fruticulosa, B. rapa ssp. Celem prezentowanych badań była identyfikacja źródeł odporności genetycznej na suchą zgniliznę kapustnych u mieszańców rodzaju Brassica, otrzymanych z krzyżowania między dwoma odmianami (Jet Neuf i Californium) B. napus i B. carinata, B. fruticulosa, B. rapa ssp. Wśród gatunków rodzicielskich najmniejszy odsetek roślin porażonych stwierdzono na odmianie Jet Neuf B. napus oraz na B. carinata.
