Variation and Correlation Studies of Vegetative and Reproductive Characteristics in Twelve Accessions of Guar, Cyamopsis tetragonoloba (L.) Taub.

Two local and ten exotic accessions of guar (cluster bean), Cyamopsis tetragonoloba were evaluated for several vegetative and reproductive characteristics. Variables studied were: plant height, number of clusters per plant, pods per cluster, numbers of pods per plant, pod length, seeds per pod, 10-seed length, 100-seed weight and seed yield per plant. Significant differences among accessions were found for all the traits studied. Results indicated that accessions 'Mirpur' and 'D-safed' can be successfully cultivated for seed production in Sindh. Seed yield was highly significantly correlated to plant height, number of branches, clusters and total pods per plant. Similarly, number of pods per plant was correlated to plant height, number of branches and clusters per plant. Correlations of seed yield with pods per cluster, pod length, 10-seed length and 100-seed weight were positive but statistically non significant.
