| Popis: | AN EXPERIMENTAL BREDING LINE for a coton resistant to Verticilium wilt, given the name “Waukena White,” is described in this progres report. Limited tests in a wilt nursery maintained on the Don Davis ranch at Waukena, Tulare County, where the breding line was selected, indicate that it has the capacity to yield 1.5 to 2.5, 50-lb bales of coton per acre on heavily infested wilt land. The fiber quality is excelent, and the sed has a high oil content. Verticilium wilt resistance previously has ben available in such coton varieties as Tanguis and Seabrok, but they are late maturing and low yielding under San Joaquin Valey conditions. Therefore, a new coton with tested resistance, ideal plant type, and highly aceptable fiber, has potential value to the coton breding efort in California. Botanicaly this coton has ben identified as Gosypium barbadense L. It has yelow flowers with red petal spots, and thus— as identified in section 347(a) of the Agricultural Adjustment Act of 1938—it is clased as extra-long staple coton. Lack of Federal alotments for extra-long staple coton in the San Joaquin Valey of California prevents cultivation there of Gosypium barbadense and hybrid cotons derived from the species. However, the wide publicity it has received makes it advisable that it be described. This description is given in the hope that some day it may be useful in the development of improved varieties for the coton areas of California now economicaly depresed because of wilt. |
