Abstract

Sorghum landraces collected from Dhadgaon and Akkalkua block of Nandurbar district were studied to assess the diversity among these landraces.  An experiment was conducted at village level in-situ conservation center during kharif season of 2016 and 2017. Morphological characterization of 13 landraces of sorghum was undertaken for 25 characters as per DUS guidelines. Traits such as anthocyanin coloured coleoptiles (53.85 %), white coloured leaf midrib (38.46 %), yellow colouration on stigma (84.62 %), grayed orange coloured dry anther (53.85 %), yellow white colour of glumes (30.77 %), semi-compact density of panicle (53.85 %) symmetrical type ear (69.2 %) grayed orange coloured seeds (53.85 %) were dominant in studied landraces. The results of present study showed that panicle branch length was most diverse trait (22.93 %), followed by 1000 grain wt. (17.23 %) and stem diameter (19.71 %) whereas leaf width showed the lowest variation (6.16 %) among studied lines. Analysis of variance showed that all the characters were highly significant among the landraces.
