irariature 4 In sone samples raature and iFiiiiature fruit could be readily 

 distinguished by ground color, but, in general, ground color differences are 

 not distinct enough to be satisiactor?- for dist:aig"o.ishDjn.g fruit of borderline 

 maturity. 



The tentative stan6:ards for naturit^^ in terms of pressure -test readings for 

 Redhaven peaches suggested in 1953 Here 13*0 pounds or less on the suture and 

 an average of l5»5 pounds or less on the cheeks. Even though peaches of this 

 firrmesE are harder than many shippers care to handle, the i-;orl-; in 19^h 

 indicated that the standaras siiould be changed to lM-*$ pounds or less on the 

 su.ture and to an average of l6,5 pounds or less on the cheeks, since peaches 

 of this firnmess ripened in 6 days or less to at least an acceptable flavor. 

 It should be emphasized that the standards proposed represent the riiniiiium 

 standards for maturity for the use of regu.latory agencies, VJliether fruits of 

 advanced or borderline maturit3^ are to be handled is a decision to be rns.de by 

 the individual shipper. 



Golden Jubilee - Golden Jubilee is another varle-'cy that is difficult to pick 

 at the right stage of maturity. Unlike Di^cLred and Redliaven peaches, the 

 fruits of Golden Jubilee sometiiiie remain, green \intil they becom.e soFiei-ihst 

 soft at the suture. The fiwits ripen rapidly and unevenly' and become very 

 soft ::hen fully ripe^ 



The tentative standards for inaturitj'' of Golden Jubilee peaches in term.s of 

 pressure-test readings suggested in 1953 were II4.0O pounds or less on the 

 su.ture and an average of 17.0 pounds or less on the cheeks, A ripening 

 period of 6 days or less iias used as a basis for maturity in this variety in 

 contrast to G days or less for the otiier varieties, Tlie >7ork in 19^h shoiied 

 that som.e of the fruit which would be scored as immature hj the 1953 

 pressure-test standards have the capacity to ripen in 6 da;'s or less. However ^ 

 since these fruits had all the subjective characteristics of imraaturity, it is 

 proposed that the pressure-test standards suggested :_n 1953 remain for field 

 trial. Our e:qoeriences with the Golden Jubilee variet;^' in C-eorgia and South 

 Carolina in 195U indicated that even imture fru.it of this variety often fail 

 to ripen to a desirable flavor after rem.oval from the tree. 



Early Ililey - Early Hiley is a wliite- fie shed variety" that is being largely 

 replaced hy nenrer, jrellow-fleshed varieties. The tentative standards for 

 maturity of Early Hiley peaches in terms of pressure-test readings suggested 

 in 1953 were 13.5 pounds or less on the suture and an average of l5«0 pounds or 

 less on the cheeks. The work in 195U indicated that these standards should be 

 changed to lli-e5 pounds or less on the suture and an average of l6,5 pounds or 

 less on the cheeks, since reaches of this firrimess ripened in C days or less 

 to an acceptable, although perhaps not good, flavor, 



Eale haven - The tentative standards for m.aturit^/ of Halehaven peaches in terms 

 of pressure-test readings suggested in 1953 were l5.0 pounds or less on the 

 suture and an average of 17 «0 pounds or less on the cheeks. The work in 195U
