Narrative

At Palmer, tests of 74 varieties from other states indicated that none was hardy enough for Alaska, even when mulched. Sitka hybrids, from Georgeson's work, that had survived thirty years, were collected and observed at Matanuska from 1950 to 1953. Crosses were first made in 1952 to obtain winter hardy, red-fruited varieties. Several hundred selfed seedlings of these hybrids were tested; also about 30,000 seedlings of crosses of Sitka D with varieties from other states ... were set in the field in Palmer. - George M. Darrow. 1966. The strawberry. p. 226.
