The Indian Journal of Genetics and Plant Breeding

The genetics of resistance to green leafhopper, [Nephotettix virescens (Distant.)] was studied in four pre-release green leafhopper resistant rice varieties viz., IET 12356 (RP 2432-98-6-3), IET 13268 (HKR 91–102), IET 15359 (SPT 6858), IET 15120 (CRM 47). The parental lines, F₁s and F₂ populations derived from the crosses of resistant varieties with the susceptible variety, TN1 or Phalguna or Sona and inter crosses among resistant varieties were screened against Indian population of green leafhopper in greenhouse at Directorate of Rice Research, Hyderabad. The inheritance of resistance suggested that two dominant complementary genes governed resistance in IET 13268, a single recessive gene in IET 15359, two recessive genes in IET 15120 and a single dominant gene in IET 12356. The single dominant gene of IET 12356 was allelic to Glh 6 in IR 64.
