| Developer: |
The ColoradoAgricultural Experimental Station. |
| Release: |
2001. |
| Tuber Shape: |
Round to slightly oval. |
| Eyes: |
Shallow, more prevalent on the apical end. |
| Skin: |
Smooth, fine-netted, very dark red. |
| Flesh: |
White, smooth but not waxy. |
| Plant: |
Small to medium and upright vine, heavily pigmented, determinate type, dark red-purple flowers. |
| Yield Potential: |
Medium to high (+400 cwt/acre). |
| Specific Gravity: |
Low to medium (1.076 avg). |
| Maturity: |
Medium. |
| Resistances: |
Hollow heart, blackspot bruise. |
| Susceptibilites: |
Overall disease problems are minimal. Bacterial ringrot foliar expression is adequate and occurs within 90 days after planting. Bacterial soft rot caused by Erwinia may be a problem in storage and in the field as seed decay and blackleg. Additional susceptibilities include foliar early blight, PVY and PLRV, although the viruses usually do not present a problem. Durango is similar to Sangre in this regard. |
| Storability: |
Durango stores well and maintains color in storage. |
| Production Mgmt: |
Durango sets about 9 tubers per plant on about 2.8 stems. A 9-inch within-row spacing has maximized total yield while maintaining a small tuber size profile, although grade components have had similar percentages at a 12-inch spacing. Due to the small vine, weed competition may be a problem for some producers. Durango has shown some sensitivity to metribuzin. Ultilize about 150 lbs. nitrogen per acre. Stolon detachment problems may result if plants are immature due to excessive nitrogen applications or if maturity is delayed due to warm conditions. Sulfuric acid use for vine kill may be warranted in such situations, to aid in stolon breakdown. Few internal and external defects have been noted. |
