Abstract

Forty three genotypes or Medicago sativa L. were evaluated for reaction to alfalfa weekly, Hypera postica (Gyllenhal) in a field test. The oviposition and larval feeding were correlated with plant characters like 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 cm. Genotypes exhibiting maximum resistance are B-15, B-22, B-135, B-209, Sirsa-9, Sarnac and Dupuits.
