Inheritance of Dry Root Rot (Rhizoctonia bataticola) Resistance in Chickpea (Cicer arietinum) uri icon

abstract

  • The inheritance of resistance to dry root rot of chickpea caused by Rhizoctonia bataticola was studied. Parental F1 and F2 populations of two resistant and two susceptible parents, along with 49 F1 progenies of one of the resistant × susceptible crosses were rested for their reaction to dry root rot using the blotting-paper technique. All F, plants of the resistant × susceptible crosses were resistant; the F2 generation fitted a 3 resistant: 1 susceptible ratio indicating monogenic inheritance, with resistance dominant over susceptibility. F3 family segregation data confirmed the results. No segregation occurred among the progeny of resistant × resistant and susceptible × susceptible crosses
