Info

• In addition to rating overall bruise susceptibility, blackspot bruise severity was rated from 1 to 5 (max. bruise) based on color intensity and percentage of the impacted area showing color (1= no bruise, 2= white knot bruise, 3= less than 50% of impact area with color, 4= >50% of impact area darkened or whole area light brown, 5= full impact area dark). A96814-65LB, RR, A98345-1 and PA00N14-2 were the most susceptible, scoring 78% bruise (stem end) in the controlled impact study. These clones also had the highest bruise severity, averaging 3.4/5. In contrast, A0008- 1TE, PA00N15-2 and A99073-1 were the most resistant, averaging only 22% bruise with a 1.5/5 severity rating. LTS • The 8- to 10-oz tubers of PA99N2-1, PA99N82-4 and A99073-1 had low length to width ratios (avg.= 1.4), resulting in yields of 3-inch or longer fries ranging from only 57 to 61% by number. For the second year, PA99N82-4 showed the greatest variation in L/W ratios, ranging from 1.7 in ID to 1.3 in WA and OR. The low average L/W ratio of PA99N2-1 was fairly consistent across states. The only numbered entries to have L/W ratios statistically equal to Ranger (2.11) and Russet Burbank (2.12) were AO96305-3 (2.21) and PA00N14-2 (2.18). The latter entry also showed the most consistent L/W ratio across production sites. • On average, reconditioning (60 o F, 21 days) tubers of A98345-1, A96814-65LB, PA00N15-2 and AO96365-2 that had previously been stored at 40 o F for 44 days resulted in the greatest improvement in fry color compared with the other clones. In contrast, AO96305-3, PA99N12-1 and PA98NM38-1 showed no reconditioning potential. • A0008-1TE, A97066-42LB, PA99N2-1 and PA99N82-4 produced the longest sprouts after 7 months of storage, considerably longer than either check (Ranger or Russet Burbank), indicating relatively short dormancy.
