Team
1. Product of six cycles of phenotypic selection for weevil resistance initiated by intercrossing 66 plants selected for low larval damage in 1957 at Raleigh, N.C. More than one-half of the 66 selected plants were from polycrosses of N.C.-selected clones tracing to plantings of polycrosses and synthetics obtained from Kansas and Nebraska in 1946. Other plants were from Narragansett, Atlantic, Rhizoma, and DuPuits. Four of the six cycles of selection were conducted in the field -- two each in North Carolina and Maryland. The fifth and sixth cycles of weevil selection were conducted in laboratory at Beltsville, Md.
2. Team, its preceding cycles, and the original lines have been undergoing field selection or observation since 1946. That information and test data indicate that it is well adapted to a considerable part of the Maryland-Virginia-North Carolina area.
3. Slower color - predominantly purple and blue with a low frequency of variegated types. Quite variable in growth habit. Fall dormancy is similar to Cherokee and Saranac. Upright growth habit but characterized by well developed axillary branching. Pods coiled, typical of M. sativa. More resistant to anthracnose, Stemphylium leafspot, common leafspot and pea aphid than other varieties adapted to mid-Atlantic area.
4. There shall be one generation each of breeder, foundation, and certified seed classes. Breeder seed production is from an isolated planting of 10,000 plants of MSHp7. A reserve of breeder seed will be maintained by Crops Research Division, Beltsville, Md. The area of production for foundation seed is defined as that north of the 40 latitude at elevations below 2,500 feet in the States of California, Nevada, Oregon, Idaho, and Washington. A request will be made to place Team in the National Foundation Seed Project.
5. Spring 1970.
