title: Races of the Barley Root-Knot Nematode, Meloidogyne naasi. II. Developmental Rates.
abstract: The developmental rates of the five newly designated races of Meloidogyne naasi were compared on barley, oat and sorghum. Races 1, 2, 3 and 4 developed and reproduced on both barley and oat but not on sorghum. Race 5 developed and reproduced readily on sorghum but poorly on oat. A more rapid rate of development of Race 5 on both barley and sorghum than that of other races on barley demonstrated that Race 5 has a shorter life cycle than do Races 1-4.
