Inheritance studies on resistance to botrytis grey mould in chickpea (Cicer arietinum L.)

Abstract

The present investigation was undertaken with the objective to study the inheritance pattern of Botrytis grey mould disease. Field experiments were conducted during the Rabi seasons of 2014-15, 2015-16 and 2016-17 at Norman E. Borlaug Crop Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar. After field screening under artificial inoculation conditions it was found that chickpea line GL10006 was resistant while lines DCP 92-3 & GNG1581 were susceptible to grey mould. Resistant line GL10006 was crossed with two susceptible varieties of chickpea i.e. DCP 92-3 & GNG 1581. GL 10006 × DCP 92-3 and GL10006 × GNG 1581 showed monogenic dominant resistance in ratio of 3R (resistant):1S (susceptible). The results showed the presence of a type of major gene resistance to grey mould in chickpea.
