Abstract
The inheritance of resistance to loose
smut was studied under artificial inoculation field conditions in crosses involving two resistant (K309
AND GHRIS ) and two susceptible (kalam and 0271) wheat cultivars . in the F1 progeny of the resistants susceptible crosses , the dominance of resistance to loose smut in both K309 and chris appeared to be dominant. Segregation of the F2
progeny of K309xkalam , kalamxK309
, K309vC271 and C271x K309 into 3 resistant : 1 susceptible plant indicated the monogenic and dominant nature of resistance in K309. Segregation ratio of 15 resistant: 1 susceptible plant in F2 progeny from the crosses involving chris showed that there were two dominant and duplicate genes controlling resistance to loose smut in this cultivar.
