1. Inca was developed by hand crossing 150 randomly selected plants from each of two improved Turkistan and flemish germplasm sources in the greenhouse. Germplasm sources had been screened for anthracnose resistance prior to crossing. A complementary strain cross method of breeding was employed.
2. It is intended that Inca be used for forage production in the country of Italy.
3. Inca is similar to Mesilla in dormancy. Its flower color is approximately 72% purple and 28% variegated.
4. Inca is moderately resistant to bacterial wilt and anthracnose. It is susceptible to Fusarium wilt and Phytophthora root rot. It has not been tested for resistance to Verticillium wilt, stem nematode, pea aphid or spotted alfalfa aphid.
5. Seed increases of Inca shall be on a limited generation basis, with one generation each of breeder, foundation and certified seed classes. Foundation fields shall be limited to a maximum of three consecutive harvest years. Certified seed shall be the first generation from either breeder or foundation and limited to four harvest years.
6. Commercial seed will first be available for sale the spring of 1987.
7. Plans are to not apply for Plant Variety Protection.
