Evaluation of rice (Oryza sativa L.) genotypes at seedling stage selected for cold tolerance under controlled conditions
Main Article Content
Abstract
Research Station under controlled conditions in 2002 to ±18°C
and relative humidity of 85 %; the behavior of rice lines and
varieties selected for cold tolerance was studied. Seed
germination, plant height and root length were evaluated at 5,
10 and 15 days. Data were statistically processed by means of
multivariate cluster analysis. Genotypes were collected in five
classes and the best ones are in the classes I, IV and III.
