Potato (Solanum tuberosum L.) production from true potato seed (TPS) has many benefits over conventional potato production in warm climates. Seedling tubers from 9 TPS families (3 females x 3 males) were produced in Beltsville, MD in 1994. Progeny from these families were evaluated under 2 different environments in a completely randomized design at Ft. Valley State Univ., GA and Presque Isle, ME in 1995. The % emergence varied between 36 (Atlantic x B0405-6) & 93 (BTD0001-12 x B0405-6) in GA. There were significant differences in tuber yields among families. Tuber yield ranged from 5.3Mg/ha to 14.3Mg/ha in GA, & from 11.0 to 13.4Mg/ha in ME. Tuber yield was significantly correlated with No. of tubers/plant, and plant vigor (r=0.85***) in GA. Average tuber yield in ME (12 Mg/ha) was greater than in GA (9Mg/ha). Families in which 'Atlantic' was the female parent were higher yielding than other families in ME. Families in which 'BTD0001-12' was the female parent were higher yielding than other families in GA. Results suggest that parents for TPS production be selected following evaluation of progeny in targeted environments. Implications of study will be discussed in relation to potato production from seedling tubers in warm & cool climates.
