56710 to 56745. Ipomoea batatas

Sweet potato. 



From St. Croix, Virgin Islands. Tubers pre- 

 sented by J. B. Thompson, agronomist in 

 charge, Agricultural Experiment Station. 

 Received March 22, 1923. Quoted notes by 

 Mr. Thompson. 



"All these seedlings were grown from seeds at 

 this station during February, March, and April, 

 1922. The seeds were collected from plantings of 

 the Big Wig, Key West 'yam,' and Black Rock 

 varieties grown close together, and it is believed 

 they may have been cross pollinated. We believe 

 that there are good possibilities even frorn these 

 -seedlings which are most unpromising." 



■56710. "No. 2. A Big Wig seedling. Vines in 

 nursery row 18 to 24 inches long, medium in 

 thickness, green with red coloring at junc- 

 ture with petiole. Leaf large, cordate, resem- 

 bling that of Black Rock; red midribs and 

 green veins. Tubers dark red. The original 

 seedling plant yielded 5 tubers weighing 6 

 pounds 6 ounces. Flesh yellow, mottled 

 with red." 



56711. "No. 3. A Big Wig seedling. In the 

 nursery row the vine growth was 2 to 4 feet 

 in length, medium in diameter, green with 

 red at juncture of petiole, and hairy. Leaf 

 3 parted, midrib and veins red, leaf growth 

 dense. The tubers are red and the first or 

 original seedling yielded 7 tubers weighing 

 1 pound 1 ounce. The color of the flesh is a 

 rich yellow." 



56712. "No. 4. A Big Wig seedling. Plants 

 in the nursery row were 5 to 8 feet long, 

 completely covering the soil. The stems 

 were rather slender, green with red coloring 

 at juncture of petiole. The leaves were 

 numerous, 3 parted with red midribs. The 

 tubers are coppery red, the flesh yellow, 

 occasionally mottled with red. The original 

 seedling bore 7 tubers weighing 2 pounds 

 8 ounces." 



56713. "No. 5. A Big Wig seedling. The 

 vines were 2 to 4 feet in length in the nursery 

 row. The leaves were cordate and resem- 

 bled those of Black Rock rather than those 

 of Big Wig, and the seedling is probably a 

 cross between these two varieties. The 

 petioles, midribs, and veins are red and the 

 tubers are a peculiar light red. The flesh 

 is white, mottled with red. The original 

 seedling plant yielded 12 tubers weighing 6 

 pounds 4 ounces." 



56714. "No. 7. A Big Wig seedling. This 

 . seedling is as yet untested. The very leafy 



vine, 3 to 4 feet long, covers the ground com- 

 pletely. The leaves are dark green, broadly 

 shouldered and lanceolate. The roots are 

 red, flesh white. Although not thoroughly 

 tested this is not regarded as a promising 

 seedling." 



56715. "No. 14. A Big Wig seedling. The 

 vines in the nursery row were 2}4 to 4 feet 

 in length, numerous, green and leafy. 

 Leaves numerous, making a dense growth

and affording a perfect covering for the 

 hill, broad, 3 parted, with long green peti- 

 oles. The midribs and veins are green, but 

 the tubers are red. The original seedling 

 yielded 4 tubers weighing only 12 ounces. 

 Flesh pale yellow, almost white." 



56716. "No. 15. A Big Wig seedling. A 

 rampant grower, vines 2 to 3 feet long, 

 numerous, stout, chocolate colored, hairy. 

 Leaves large, broad, pointed, very dark 

 green, petioles green tinged with red, 10 to 

 12 inches long on old growth, midribs and 

 veins red. Tubers dark red, flesh pale 

 yellow. Original seedling yielded 2 tubers 

 weighing 8 ounces." 



56717. "No. 18. A Big Wig seedling. A 

 rampant grower, the vines reaching out 8 

 or 10 feet on each side of the nursery row. 

 This variety flowers profusely. Tubers 

 red, flesh pale yellow. Not considered 

 very promising." 



56718. "No. 19. A Big Wig seedling. Vines 

 in nursery row 18 to 24 inches long, bearing 

 a dense growth of finely cut leaves. Leaves 

 deeply cut and lobed, 5 parted, midribs 

 red, veins green to wine colored. The 

 tubers are dark red and the flesh a golden 

 yellow sometimes mottled with red. Origi- 

 nal seedling plant had no tubers." 



56719. " No. 20. A Big Wig seedling. In the 

 nursery row the stems were from 2 to 4 feet 

 long and numerous. The leaves were 

 numerous, dark green, with red midribs 

 and veins. The original seedling plant 

 yielded 6 tubers weighing 10 ounces. The 

 tubers are a dark red with pale-yellow flesh 

 sometimes mottled with a little red." 



56720. "No. 22. A Big Wig seedling. In 

 the nursery row the vines were slender, 2 

 to 4 feet in length and moderately leafy. 

 Leaves broad, relatively short, pointed, 3 

 parted, midribs and veins green. Flesh of 

 tubers deep yellow. The original seedling 

 plant bore 12 tubers weighing 3 pounds." 



56721. "No. 24. A Big Wig seedling. In the 

 nursery row this vine was medium stout, 

 3 to 4 feet in length, leaves medium size, dull 

 green, 3 and 5 parted (usually 3 parted). 

 The tubers are light red, irregular in form, 

 and show a tendency to burst and split 

 badly. The variety shows a tendency also 

 to produce tubers at the joints where they 

 root, even at a distance from the hill. The 

 original seedling plant produced 33 tubers 

 weighing 13 pounds 8 ounces and was the 

 heaviest producing hill among all the 

 original plants. The flesh is pale yellow." 



56722. "No. 26. A Big Wig seedling. In 

 the nursery row this seedling shows short 

 vine growth with rather sparse foliage . The 

 stems are short and stout, attaining a maxi- 

 mum length of 2 to 3 feet. The leaves are 

 lanceolate with a wine-colored midrib. 

 The tubers are dark red and grow at the 

 ends of fleshy roots that are 12 to 18 inches 

 long; flesh white. The tubers are traversed 

 by a number of pronounced ribs or veins. 

 The original seedling yielded 4 pounds of 

 tubers under very adverse conditions." 



56723. "No. 28. A Big Wig seedling. Stems 

 rather slender, 2 to 3 feet in length, green 

 and leafy. Leaves broad, 3 parted, midrib 

 wine colored. Tubers long, white, smooth, 

 and hanging on roots in a cluster around 

 the main stem, flesh creamy yellow. The 

 original seedling plant produced 13 tubers 

 weighing a total of 3 pounds 4 ounces." 



56724. "No. 29. A Big Wig seedling. Stems 

 short, stout, leafy, covering the ridge well, 

 but not having sufficient length to com- 

 pletely cover the full area between rows. 

 Leaves large, broad, 5 parted, midribs and
