Genetics of bushy growth habit and its implications in chickpea improvement

Abstract

Chickpea (Cicer arietinum L.) plant is generally erect, semi-erect, spreading, semi-prostrate or prostrate (mainly wild annual Cicer species) in growth habit depending on the angle of branches arises from the vertical axis. Spontaneous mutations are the source of genetic variability and have resulted into dwarf erect compact type plants with high number of branches arising from base, commonly called as “bushy mutants” in chickpea [1-3]. In a study [4], it was reported that mean yield of the lines with bushy growth habit, across all environments, was higher than that of the erect habit lines..
