History

     Selection from Grand Bay, Ala. with a large-sized nut of high quality.

Comments

Planted in 2002 and bore its first small crop in 2005.  Cherryle produces an attractive nut with excellent fill.  Nut size is large and shells are thin giving a high percent kernel.  Kernel color can be a little on the dark side, but not too bad.  We have rated this one as excellent in terms of kernel quality each year.  Scab has been present, but controlled with a full season spray schedule.  In 2005, our highest pressure scab year, leaf and nut scab were rated as mild whereas 'Desirable' had serious quality loss from scab pressure.  Our biggest concern, so far, has been low to moderate yields.  This seems to occur because the young trees typically bear on interior shoots instead of terminal shoots.  However, in 2009 yields were good and higher than Desirable.  This appears to be a cultivar that takes a little time to come into production and definitely is not a precocious cultivar.  Suture split can be seen in some years (see picture below).  Right now we are recommending this cultivar for trial only until we know a little more about the productiveness of mature trees.   'Cherryle' is a type II (protogynous) cultivar.
