It is probably the "etanderd'variety <br />~.,i Colorado at the present time. It ie a variegated variety synthesized <br />gcrom five different clones (crown cuttings). It hen high pield capacity <br />and responds well to good culture. It !e somewhat susceptible however, to <br />the leaf spot disease. • <br />Vernal: Vernal is a USDA-Wisconsin variety of complez synthesin. <br />Pifty percent of .the clonal parentage, however, wee from the old variety, <br />Cossack. Vernal ie very hardy end is resistant to both alfalfa wilt sad <br />to the leaf spot disease. It has high yield capacity. Growth habit in <br />the field is very similar to Ranger. <br />Lahontaa. Lahontan le included herewith beceuee of the fact that it <br />was our first variety which contsined zeaistence to the alfalfa aphid. <br />there 1e still a subetantiel acreage of the variety being grow, particu- <br />larly in the Atkaneee Valley. <br />Lahonten. a USDA-Nevada release was actually developed ae a nematode <br />resistant variety, but the insect resistance wan also discovered ee the • <br />five clone synthetic was selected. It produces a good quality hay sad the <br />growers like it. It ie reaietsnt to the stem nematode and to the ephid~ <br />but highly susceptible to leaf disease. <br />Washoe. Waehoe is very similar to Lahonton in all characteristice~ <br />but it has a little more capacity for yield. It renters the pee aphid <br />ea well ae the alfalfa aphid and etem•nematode. It ie also a wilt re- <br />eietant variety. <br />Narragansett. Phis variety resulted from a complex synthesis of <br />~~native (common), falceta~ and Canadian variegated clones. It became prominent <br />' when it proved to be the only variety to survive after a 1944 tornado re- <br />sulted in the entire alfalfa teat being submerged in sea water for a long <br />period of time. Seed of this variety was produced under the certification <br />program for Hew York state during the I950'e. There ie still a smell <br />acreage of the variety in Colorado. <br />Atra. Atra is a selection from Vernal which originated in California. <br />Like Vernal it is herdy~ resistant to leaf spot and wilt resistant. <br />Dawson. Dawson ie a Nebraska variety. It ie a synthetic. developed <br />from eight clones each of which vas selected for resistance to aphids. <br />+ Davaon ie resistant to both the alfalfa aphid and to the pea aphid. It <br />has excellent yield capacity and it's hardiness is about the same ae ~ <br />Ranger. <br />Cody. Cody ie a Kansas variety selected from 22 parent clones of <br />Kansas Common (similar to Buffalo). It is a purple flowered variety <br />similar to Buffalo in all characteristics except that it is resistant to <br />the alfalfa aphid. Aardineee ie only moderate, eo it fe recommended only <br />in the southern portion of the state. <br />Ranza. Ranza has the same general background ae Cody, but ft has <br />been selected for greeter yield capacity, It la doubtful that you can <br />tell it from Cody in the field. <br />
