Resistance of Barley (Hordeum vulgare L. Emend. Lam.) Cereal Leaf Beetle (Oulema melanopus L.)1

Sang Ki Hahn2

The cereal leaf beetle, Oulema melanopus L., was first identified in North America at Galien, Michigan, in 1962. Shortly after identification, the search for host resistance of barley Hordeum vulgare L. emend. Lam., was initiated. On the basis of the field and laboratory screening results, eight parental lines were selected to make a diallel cross set in order to investigate the genetic basis of resistance. The progenies from six parents were used in the laboratory, and the progenies from the eight parents were tested in the field. In addition, the back-cross Larker 2x CI 6671 was made.

The F1 progenies from the 6-parent diallel were tested for resistance in the laboratory. The F2 progenies from the 8-parent diallel and from the backcross were tested in the field.

The resistance to cereal leaf beetle in barley appears to be recessive. The mechanism seems to be due to both nonpreference of the barley plant by feeding larvae and differential egg laying.

The most resistant combination from the 8-parental diallel cross was CI 6671 x CI 6469. Transgressive inheritance was found in the cross of these two lines which indicates the possibility of obtaining higher resistance.

Key Words: diallel • genetics
