Forty three genotypes or MecIic¥J .tiva L were evaluated ror readio.. to alfalfa weeYiJ, Hypera
postica (GyUenJlal) In a neldtest. The oviposition and larval feeding were correlated with plant
characters Uke height, stem diameter and crown width. The damage Increased with Increase in
stem girth and plant height, while it decreased with increase in crown width. The most resistant
types possessed stem diameter of 1.00-1.33 mm and crown width of 4.67-6.00 em. Genotypes
exhibiting maximum resistance are 8-15, 8-22, ~- 135, 8 - 209, Slrsa- 9, Samac: and Dupuits.
