The establishment of intergeneric hybrids for horticultural and agricultural crops is still a demanding task for breeding programmes. The aim of such approaches is to introduce new quality and resistance traits and to enlarge the gene pool. Recently, an F1 hybrid between Malus × domestica and Pyrus communis became available which arose from a breeding approach undertaken in the late 1980s by the breeder...
Histochemical screening of 30 Rosaceae genera representing all classic subfamilies demonstrated flavan‐3‐ols (catechins) as general secondary metabolites in roots of Rosaceae. Semi‐quantitative LC‐MS analyses confirmed the presence of catechin, epicatechin and various dimeric flavan‐3‐ols (also representing higher polymeric proanthocyanidins) as prominent polyphenols in root tips of Fragaria (strawberry),...
Pear (Pyrus sp.) is a major fruit crop of temperate regions with increasing extent of cultivation. Pear flavonoids contribute to its fruit color, pathogen defense, and are health beneficial ingredients of the fruits. Comparative Southern analyses with apple (Malus x domestica) cDNAs showed comparable genomic organization of flavonoid genes of both related genera. A homology-based cloning approach...
