David Chaney
The primary efforts in 1978 were {1} to try to deter:rrine whether timeof ha:ntest and related naturity factors influence the qual.ity grade ofprocessed #7O7 French prunes, and (21 to determine the pittability ofseveral French prune selectiorrs.
to deterrrine the influence of hanrest ti:ning on quality, about 6O poundsof fresh #7O7 French prunes from two blocks lrere picked separately atweekly intsnrals for five weeks, dehydrated, stored and then processedand evaluated by expert prune industry personnel in mid-Novenber. Samptesof i.nproved French of sjrnilar age and growing adjacent to one of the*7O7 blocks were si":niJ,arly co1J.ected, handled and evaluated.
of the total of ten #7O7 French and five improved French sanples, fourof, the five inproved French samples brere judged to be of Santa Claraguality, while onJ.y one of the ten #7O7 French samples merited SantaClara quality. The earliest picked improved French sample rras Californiaguality while the Santa Clara guali.ty #7A7 French sample was harvestedin nid season" Skin peeling appeared to be the primary d,efect of the*7O7 that resulted in California grade on all but one sample.
One green bin lots of #7O7 French were hanrested for pitting evaluationfrom five different growers blocks at various stagres of the hanrest s€€l-son. In addition' one bin lots of Woods Red French, Woods Black Frenchand improved French were also harvested for pitting.
.
Results of the pitting tests showed that all four of those French pruneselections pitted satisfactorily. Quality evaluation results with the#707 French indicate that it may have an inherent skin characteristicthat reduces its appearance quality in relation to improved French whenprocessed by current industry procedures.
