Title: Re: [NAFEX] pseudomonas resistant apricot? (was St. Julian ...)

The biggest problem with apricots in the NW is that they bloom so early that it takes a rare spell of warm dry weather during bloom to get anything.  Sometimes you can save them if you spray heavily to kill the pseudomonas, but the early blooming still causes other problems.  What is needed is either an apricot with very high resistance to Pseudomonas, or one that blooms much later than average.  There ARE late blooming forms of apricot, but none of the commercially available.  I have been growing seedlings of Mormon Chinese which is an old heirloom vareity.  Some of them bloom nearly a month later than normal 'cots and I do get a crop now and then from them.
