Collection and Characterization of Paddy Germplasm in High Altitude and Tribal Area Zone of Visakhapatnam

A study was conducted on characterization of paddy germplasm of high altitude and tribal area zone of Visakhapatnam district during the year 2000–2001. 81 germplasm entries collected from the tribal areas of the district were characterized for 18 growth and yield attributing characters. Among the eleven characters, green leaf sheath, glabrous leaf moderately exerted panicle, with short and partly awned grain, straw-coloured hull having easy threshability were noticed to have higher absolute frequency. Aroma was present in 32 per cent of the entries. Correlation studies have revealed a significant and positive correlation of grain yield per plant with days to flowering, days to maturity, leaf length and aroma.
