Apple ( X Borkh.) is one of the world's most valuable fruit crops. Its large size and long juvenile phase make it a particularly promising candidate for marker-assisted selection (MAS). However, advances in MAS in apple have been limited by a lack of phenotype and genotype data from sufficiently large samples. To establish genotype-phenotype relationships and advance MAS in apple, we extracted ...

The project ‘Mycorrhizal symbioses of transgenic apple trees with increased resistance against fungal pathogens’ (Subproject of the framework ‘Biosafety of transgenic woody plants’, supported by the German Federal Ministry for Education and Research) investigates whether the transformation of apple trees with fungal chitinase encoding genes besides increasing resistance against fungal pathogens...

relative resistance of 43 iranian as well as introduced apple cultivars to blue mold (penicillium expansum) was studied within years 2010-2011. the fruit physicochemical traits were also evaluated as measures of potential resistance to decay. local p. expansum strains were isolated from decayed apple fruits and the most aggressive isolate (5,000 spores ml-1) used as inoculum. fruits were wound-...

In grafted apple combinations, rootstocks can increase the stress tolerance of plants, influence scion growth, and harbor a rich microbial community. However, whether scions modify plant rootstock phenotypes rhizosphere bacterial communities has not been clearly investigated. Here, 14 different combinations two cultivars on 7 genotypes were used as research materials, we analyzed traits, commun...

ABSTRACT Botrytis cinerea is an economically important pathogen. Epidemiological studies are difficult because of the genetic variability within this species. The objectives of this work were to study the variability and to compare the inhibitory effects of Ca on three isolates of B. cinerea from decayed apple (B) and grape (C and C77:4). Among these isolates, B had the least radial growth but ...

Jablká patria medzi najviac konzumované ovocie na svete. Európska únia je po ?íne jedným z najvä?ších producentov jab?k. Vzh?adom vhodné pôdne a klimatické podmienky Po?sko popredným producentom týchto plodov vo svete Európskej únii. V sú?asnosti kultivarová štruktúra európskom trhu obmedzená približne 12 odrôd. To vedie ku genetickému ochudob?ovaniu strate mnohých miestnych kultivarov, ktoré p...

This study examined the effect of debagging time on color and flavor / taste compounds in the non-red apple cultivar 'Golden Delicious' and red cultivar 'Qinguan' at mid and late stages of fruit development. Debagging briefly improved the red color in both cultivars, the peel of 'Golden Delicious' presenting pale-pink hue. However, rapid anthocyanin accumulation occurred in apple peel at a spec...
