Abstract
Roots of the ‘Centennial’ variety of Ipomoea batatas Lam. were sectioned and treated with dimethyl sulfoxide (DMSO), Captan, Semesan Bel, and combinations of these chemicals using 5 soaking intervals. A significant difference was found between the effects of chemicals in number of plants produced and mean weight of plants. Combinations of chemicals were better in both cases than chemicals used independently. DMSO treatments yielded significantly more plants than Captan or Semesan Bel treatments; however, the 3 single chemicals produced plants of similar mean weight. Whole roots produced significantly more and a higher average weight of plants than individual root sections. Soaking time had no effect upon number of plants or mean weight of plants.
Abstract
‘Rojo Blanco’, a new cultivar of sweet potato (Impomoea batatas Lam), has been released by Tuskegee Institute for the Latin trade in New York, Chicago, and Denver marketing areas, as well as Latin American countries. ‘Rojo Blanco’ should be considered a substitute for the ‘Boniato’ or ‘Cuban’ sweet potato, which is rough, veiny, produces less than 5% U.S. no. 1 roots and does not store well. ‘Rojo Blanco’ is intermediate in resistance to fusarium wilt, (Fusarium oxysporum f. sp. batatas), which is comparable with that of ‘Centennial’ and therefore, should be satisfactory for most growing conditions. It is susceptible to the southern root-knot nematode, (Meloidogyne incognita), (Table 1).
Abstract
The ‘Carver’ sweet potato (Ipomoea batatas Lam) has been released by Tuskegee Institute to fill a need for a cultivar possessing high resistance to fusarium wilt, Fusarium oxysporum f. sp. batatas, and intermediate resistance to the southern root-knot nematode, Meloidogyne incognita. ‘Carver’ is a dual purpose cultivar, suited for both fresh and processing market (Fig. 1), and it is well adapted to Alabama growing conditions.
Abstract
Seedlings of sweet potato [Ipomoea batatas (L.)], which failed to form storage roots, produced good yields of sweet potato roots of acceptable size and grade when propagated asexually by vine cuttings.
