The experiment was conducted in Boro 2001-02 with 20 varieties. Mahalanobis D2 –values were determined and the varieties were grouped such that the varieties within a group are similar while varieties in different groups are dissimilar. Panicle length (PL) was found to be the most variable plant character with CV=25.7% for rice yild.From the analysis of variances of rice yield and different plant characters, Panicle length (PL) was found to be the most variable plant character with CV=25.7% followed by effective tillers /hill (TN) with CV = 19.9%. Days to 50% flowering (DAF) was the least variable character with CV=0.7% followed by 1000 grain weight with CV= 1.8%. For all plant characters, the F-values were significance at 1% level except panicle length, which was significance at 5% level.

  Classification
  1. To determine the relative contribution of phenotypic characters to rice yield
  2. To classify BRRI varieties based on phenotypic characteristics

The experiment was conducted in RCBD with three replications. The plot size was 5m x 2m. In each season, recommended BRRI varieties was grown under optimum management practices. All phenotypic characters were recorded. Available multivariate techniques was used to analyze the data.
