Phenotypic characters of rice landraces reveal independent lineages of short-grain aromatic indica rice

Crop domest­ic­a­tion is a remark­able example of the evol­u­tion of wild plants into cul­tiv­able forms through human selec­tion. Following the domest­ic­a­tion of rice almost 10,000 years ago, ancient farm­ers selec­ted many rice lin­eages for diverse agro­nomic and cul­tural traits, such as grain size, shape and col­our; awn length; pest res­ist­ance; and aroma. A recent study in AoB PLANTS by Ray et al. examined the phen­o­typic traits of a large col­lec­tion of Indian rice landraces (all accessed from Vrihi, rice seed bank, www​.cint​dis​.org/​v​r​ihi) and found that a few grain, pan­icle and leaf traits are major drivers of the huge phen­o­typic diversity observed. They also demon­strated the exist­ence of short grain aro­matic landraces per­haps with inde­pend­ently evolved aroma traits. The inde­pend­ent ori­gin of aroma in indica rice is fas­cin­at­ing as it explores lesser known aspects of indica rice domest­ic­a­tion and diversification.
