INDEXING FOR FLAT LIMB AND LINE PATTERN |
| Author: | G. Schmid |
| Abstract:
Flat limb Double budding was as good an indexing method for flat limb as double grafting. The indicator 'Gravenstein' reacted better than 'Stahls Prinz' and 'Idared' with the source used. Most trees showed symptoms the second year after inoculation, some the 3rd and 4th year, and one the 5th year. Only 4 trees out of a total of 126 surviving after 5 years did not show any symptoms. Line pattern 'Ersinger' was a better indicator for 3 line pattern type source than 'Pozegaca' and 'Shiro' plum. | |
