Abstract
Differences between clonally-propagated interspecific hybrid chestnut rootstocks were observed when short-term graft compatibility with four Italian cultivars of ‘Marrone’ was investigated.
The rootstock clone CA07 had the highest overall percentage of successful grafts.
It had an “excellent” compatibility rating with two of the ‘Marrone’ cultivars but “good” or “poor” ratings with the other two.
CA15 had a lower percentage of graft success than CA07 but the unions formed were rated as “good” for all four ‘Marrone’. The success rate for CA74 was worse than that for CA07 and CA15 and its compatibility ratings ranged from “good” to “poor”. As rootstocks for ‘Marrone’ the clones CA90 and CA118 were almost total failures.
