In most of the countries where sweetpotato is grown, it is a food produced by small-scale
farmers with limited resources and peripheral soils. Under these conditions, the amount
of the crop and the commercial availability of tubers are associated with the sum of small
yields. However, the production potential per area achieved by small producers is below
the average obtained by large producers in developed countries. In this respect, it is
important to emphasize that there is a window of possibilities for the small producer to
achieve higher yield with the adoption of improvements in relation to crop management,
as well as in the availability of seed-branches generated from cultivars from genetic
improvement. In this sense, the work aimed to evaluate the commercial production of
new materials obtained from promising sweet potato crosses. The experiment was
conducted in randomized blocks with 10 treatments (one commercial cultivar (SCSXXX
Ituporanga and nine new materials (17162, 17025, 17107, 17052, 17125, 18205, 18114,
18401, kati_roxa)), three replications and seven plants per plot, being the five central
plants evaluated for the commercial production characteristic. To separate the materials,
analysis of variance and Tukey's test of means at 5% probability of error were performed
using the R computer application. There was a significant effect for the treatments, six of
the nine new materials were superior in relation to the cultivar and two did not differ from
it. The material 17162 was the one that produced more commercially (75.15 ton.ha-1)
differing from the other materials (between 35.88 and 55.47 ton.ha-1). MenosIn most of the countries where sweetpotato is grown, it is a food produced by small-scale
