Assessment of Character Contribution to the Divergence for Some Rice Varieties

M.R. Zaman, D.N.R. Paul, M.S. Kabir, M.A.A. Mahbub and M.A.A. Bhuiya
Fifteen modern rice varieties were grown in Aman seasons of 2002 and 2003. On the basis of data on days to 50% flowering, 1000-grain weight, plant height, flag leaf area, yield, field grain per panicle, tiller number per hill and flag leaf angle in the lower portion, characters like days to 50% flowering and 1000-grain weight made the largest contribution to the total divergence. After excluding less contributory characters to the total divergence and Mahalanabis D2 values were calculated, then identified the most three distant and closest pairs. From the distance matrix tables of Mahalanabis D2 analysis, (BR10, BRRI dhan30) was found as the closest pair and (BR5, BRRI dhan33) was found most distant pair. It was estimated that among the Aman varieties, yield, tiller number per hill, filled grains per panicle were the less contributing characters towards the total divergence. Breeding for the improvement of those characters, therefore, have the little possibility. However, there is a scope to improve days to flowering using those varieties.
