Diversity Analysis in Clusterbean [Cyamopsis tetragonoloba (L.) Taub.]

摘要

Clusterbean [Cyamopsis tetragonoloba (L.) Taub.], locally known as guar, belongs to family Leguminoseae, is a multipurpose drought-tolerant crop grown primarily in India and Pakistan for feed, green fodder, vegetable, green manure and grain purposes.The findings that clusterbean seed endosperm could be a source of industrial gum brought this little known arid legume crop paved its way to be the crop of major prominence. The nature and magnitude of genetic divergence in a population is essential forselection of diverse parents which upon hybridization leads to a wide spectrum of gene recombination for quantitatively inherited traits (Singh et ah, 2005). Therefore, the present study was undertaken to assess genetic diversity available in released varieties and a few breeding lines of clusterbean so as to identify diverse parents for hybridization programme.
