Diversity Analysis in Rice Using GENSTAT and SPSS Programs

Abstract

A study was conducted to assess the morpho-physiological divergence among 21 T. Aman rice cultivars at BRRI regional station, Sonagazi, Feni, during July 2008 to December 2008. Data were collected on 13 morphological and 14 physiological traits. Cluster analysis were carried out separately by using two softwares viz. GENSTAT v 5.5 and SPSS v 12.0 where in, both the software divided the cultivars into five clusters in both cases. The resulted clusters seemed to be very similar to some swapping genotypes which indicate that the softwares showed little dissimilarity. When clusterings were carried out using 13 morphological data, multivariate analysis showed five clusters in both GENSTAT and SPSS software with 19.05% swapping genotypes. When multivariate analyses were done with GENSTAT and SPSS softwares based on 14 physiological data, five clusters were also found with 14.29 % swapping genotypes. Of the two programs, GENSTAT appeared to be more reliable than the SPSS program. Inclusion of BR3, BR5, BR11, BR23, BRRI dhan33, BRRI dhan38, BRRI dhan44 and BRRI dhan46 giving emphasis on BRRI dhan33, BRRI dhan38, BRRI dhan44 and BRRI dhan46 is recommended for effective development of a breeding strategy in diallel fashion.
