Fig 4.
Genetic differentiation of 192 rice landraces/genotypes from Chhattisgarh, India based on principle component analysis.
Note: Blue diamond represents rice genotypes that include Dongjinbyeo, ‘close to japonica’ and ‘intermediate’ type of landraces. Red circle represents remaining ‘intermediate’ type of landraces which have more indica allele. The black circle represents all the ‘indica’ and ‘close to indica’ type of rice landraces including Swarna, Mahamaya and Rajeshwari varieties.

Dendrogram depicting the genetic diversity of 190 rice landraces/genotypes from Chhattisgarh, India based on cluster analysis.
Note: Blue colour represents rice genotypes that include Dongjinbyeo, ‘close to japonica’ and ‘intermediate’ type of landraces. Red colour represents remaining ‘intermediate’ type of landraces which have more indica allele. The black colour represents all the ‘indica’ and ‘close to indica’ type of rice landraces including Swarna, Mahamaya and Rajeshwari varieties.
