Peltier, George L. (1933) The relative susceptibility of alfalfas to wilt (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 66)


ISSN 0097-1397


Except for alfalfa seed originating from a few old fields of Turkestan and Ladak, all varieties and strains now grown for commercial seed production in the United States, so far tested, have proved susceptible to wilt. All seed lots tested from South America (Chile, Argentina, and Uruguay), Europe (France, Spain, Portugal, Germany, Hungary, Italy, Roumania, and Ukranian S.S.R.), Africa (Morocco, Algeria, and Abyssinia), and Asia (Palestine, Manchuria, China, Korea, and Chinese Turkestan) were found to be susceptible to wilt. All seed lots of Turkestan origin so far tested are as resistant as Hardistan, or more so. Seed samples from the following districts of Turkestan, in order of combined wilt and cold resistance, ranked thus: Khiva, Chimbai and Alma Ata, Tashkent, Samarkand, and Chardzhui. Seed from the Bukhara, Ashkhabad, and Ferghana districts while wilt resistant lacked sufficient hardiness. Similarly several seed lots from Persia and one from India, although wilt resistant, lack sufficient hardiness.
