Abstract
Cultivar choice is important for the success of fruit orchards.
In France, cultivars were assessed in 4 locations with different pedoclimatic conditions.
Cultivars were evaluated according to tree management technicity, phenology, productivity and fruit quality attributes (appearance, texture and flavour). Brown rot, caused by Monilia spp., is a major problem in peach and nectarine production because of the preharvest and postharvest damage.
Producers are increasingly left with fewer control options, particularly following the withdrawal of certain active ingredients and poor efficacy of alternative products.
Little is known about cultivar susceptibility across different environments.
A study conducted from 2009 to 2020, within the framework of the evaluation network of new peach cultivars, compared the susceptibility of nearly 240 cultivars.
A common postharvest protocol was established (60 fruit samples, 2 days storage at 8°C, then continued storage at 21°C and 80% RH). Even if no resistant cultivars were identified, this study has led to the acquisition of knowledge on the behavior of recent cultivars.
These results should prove very useful to growers when choosing their cultivars, due to the future challenges they face of developing environmentally friendly production systems and the withdrawal of certain plant protection products.
Following white and yellow flesh nectarines cultivars: NECTASWEET® NECTARLAM cov, PRIME PEARL cov, SF 11.308 cov, NECTAPOM® Nectapink cov were identified as less susceptible to brown rot.
Considering white and yellow flesh peach, cultivars BELLERIME® Maillarime cov, MELISSA cov, MAREVA cov, SF 08.179 cov and PAMPANA cov were identified as having the lower susceptibility to brown rot.
