Fig. 2From: Genetic differentiation and restricted gene flow in rice landraces from Yunnan, China: effects of isolation-by-distance and isolation-by-environmentUnrooted neighbor-joining trees of the rice landraces from 28 locations based on Nei’s genetic distances in japonica (a) and indica (b) groups. Colours for rice landraces collected from different locations: red, from northern locations (N); green, from southern locations (S); blue, from middle locations (M)Back to article page
