ICGVs 86252, 86393, 86455, and 86462 are high-yielding, jassid-resistant breeding lines w i t h agronomic characteristics superior to those of their jassid-resistant parents, NC Ac 2214 and NC Ac 2240. They are also less susceptible to thrips.

Origin and Development

These breeding lines were developed using the bulk pedigree method, from crosses made in 1982 between high-yielding breeding lines/cultivars and jassid-resistant germplasm sources. The jassid resistance sources, NC Ac 2214 (ICG 5040) and NC Ac 2240 (ICG 5043), are also resistant to thrips and termites, but have several undesirable agronomic traits including low yield potentials. The pedigrees of the breeding lines are: ICGV 86252 = (ICGS 7 x NC Ac 2214) F2-B1-B2-B2-B3-B3 ICGV 86393 = (J 11 x (M 13 x NC Ac 2214)) F 2-B1-B1-B1-B1-B2 ICGV 86455 = ( K a d i r i 3 x (M 13 x NC Ac 2214)) F 2-B1-B1-B1-B2-B2 ICGV 86462 = (ICGS 1 x NC Ac 2240) F 2-B2-B2-B3-B4-B2
