Abstract:
Background: Protein requirement is essential for human growth and development and pulses play a dynamic role in providing protein fulfillment in the human diet. In pulses, Pigeonpea is the second most important crop. It has been recommended for a balanced diet with cereals, especially to fill the nutritional gap for proteins. This crop also possesses medicinal properties and is being used in traditional ways as a medicine. Pigeon pea has diversified uses such as food, feed, fodder, and fuel wood. Also, act as a check for soil erosion and maintain soil fertility. It is a hard, widely adapted, and drought-tolerant crop.
Method: The experiment was conducted on 30 pigeonpea genotypes in the central plain agro-climatic region of Uttar Pradesh in RBD with three replications. Twelve different traits were included in the study. Observed data were analyzed using SPAR 3.0 (Indian Agricultural Statistics research institute ICAR- IASRI).
Result: Based on D2 statistics, six clusters were formed from 30 genotypes by ‘Tocher's method’ and the clustering pattern indicated that genotypes were clustered irrespective of their eco-geographical regions. The generalized Inter-cluster distances in the present investigation ranged from 1640.023 - 11271.322 and the Intra-cluster D2 values showed noticeable differences ranging from 0 to 922.520. Cluster Ist was the largest comprising 18 genotypes, followed by cluster IInd which accommodate 6 genotypes. Clusters IIIrd and IVth comprised 2 genotypes each. Clusters i.e., Vth and VIth out of six clusters were mono genotypic as they accommodate single genotypes. Superior genotypes selected based on Inter-cluster distance and cluster means could be utilized in the exploitation of heterosis and for the hybridization program.
