Narrative
NC 4 was the first peanut cultivar released by North Carolina State University. It was selected by Mr. P.H. Kime from among 100 plant selections he made in farmer stock peanuts collected from various peanut-growing counties in the state in 1929. The seed lines derived from the 100 selections were tested from 1936 through 1944, and Line 4 was identified as a typical Virginia bunch type. NC 4 was never formally released, but seed was distributed to growers on an informal basis. This method of plant breeding, called “mass selection” or “pure-line selection,” was common in the early part of the 20th century when most cultivars of crops still had substantial genetic variability within them. Pure lines contain very little residual genetic variation; the vast majority of the variation is between rather than within lines. Once pure line cultivars proliferated, there was little additional progress to be made by selecting within them. Although some breeding projects continued to release cultivars selected as “sports” or mutants occurring naturally within existing cultivars, any substantial progress had to come from hybridization and selection with the hybrid populations
