Registration of ‘Wrangler’ Alfalfa

Resistance and susceptibility of alfalfa (Medicago sativa L.) cultivars to the aphid Therioaphis maculata (Homoptera: Aphididae): insect biology and cultivar evaluation

“…Four resistant cultivars, CUF 101 (Nielson & Lehman, 1977); Baker (Kehr et al, 1978); Mesa-Sirsa (Schonhorst et al, 1968); and Lahontan (Howe & Smith, 1957); two susceptible cultivars, ARC (Devine et al, 1975); Caliverde (Nielson & Lehman, 1977); and an important Brazilian cultivar, Crioula (Nuernberg et al, 1992) were cultivated in small garden plots (7 m 2 ) at the Biology Department of the FFCLRP-USP, Brazil (21 05 to 21 15 S and 45 50 to 47 55 W). All cultivars were also cultivated under laboratory conditions in polystyrene trays (5 cm 5 cm 7 cm) filled with a mixed vegetal matter and expanded vermiculite substrate (Bioplant).…”
