Variation in resistance mechanisms to the green peach aphid among different Prunus persica commercial cultivars.
ABSTRACT Peaches and nectarines are frequently attacked by the green peach aphid Myzus persicae (Sulzer), with significant negative impacts on fruit production. The genetic variability of resistance to this aphid among commercial cultivars of Prunus persica (L.) Batsch and Prunus persica variety nectarina was evaluated in this study. In total, 16 cultivars of P. persica were selected to evaluat...
متن کاملPeach (Prunus persica) endopolygalacturonase cDNA isolation and mRNA analysis in melting and nonmelting peach cultivars.
Two distinct partial cDNAs, PRF1 and PRF3, similar in sequence to previously described polygalacturonases, were amplified from ripe peach (Prunus persica L. Batsch cv Flavorcrest) fruit cDNA by the polymerase chain reaction. PRF1-related RNA was present in fruit from early ripening at levels not detected by northern analysis. PRF3-related RNA was readily detectable in ripe fruit by northern ana...
متن کاملPhysiological and Taxonomical Studies on Some Peach Cultivars
This study was conducted during two successive seasons 2003 and 2004 by using twelve peach cultivars whether importedlow chill or originated as strains of local cultivar Meet Ghamr. Studied cultivars were either early-season ones (namely, Robin, Rubidoux, and Spring Time) or mid-season cultivars (namely, Florida Red, Fla 16/33, Fla 3/2, Desert Red, Bemto, and Hagazy) or late-season cultivars (n...
متن کاملNematodes attacking cultivars of peach in north Carolina.
Criconemoides xenoplax and Meloidogyne incognita were the nematode species most frequently associated with peach in North Carolina. Other nematodes often found in high numbers on that crop were Pratylenehus vulnus, Helicotylenchus spp., Trichodorus christiei, Xiphinema amerieanum and Tylenchorhynchus claytoni. P. vulnus and P. penetrans reproduced well on rootstocks of 21 peach cultivars tested...
متن کاملEffect of Peach Cultivars, Rootstocks and Phytophthora on Iron Chlorosis
The cultivar and rootstock effect on iron chlorosis were studied. The results revealed significant differences among peach cultivars and rootstocks in mineral content. Seasonal changes were also found in the macroand micronutrient content of leaves of peach cultivars and rootstocks. The rootstock St. Julien 655/2 was found to be efficient in K, P, Zn, Fe, Cu absorption and better than seedling ...
