Growth Variability and Correlation Studies inDolichos biflorusL. at Two Locations

Abstract

Thirty accessions of Dolichos biflorus L. were sown in two different locations viz., Crop Research Farm (CRF), under the Department of Botany of the University of Burdwan and Gagnabad, Adra, Purulia following a Randomized Block Design (RBD) layout having four replications. These accessions were collected from National Bureau of Plant Genetic Resource (NBPGR), New-Delhi, during September, 2010. Seeds were sown in the field in the month of November 2010. Uniform agronomic measures were provided in both the locations for the proper growth and development of the crop. Various metrical characters were observed and all the data were recorded properly for further computations. Correlation analysis was performed among measured characters. Out of thirty accessions, seven genotypes proved themselves to be the most adaptive in both the locations of different agro-climatic conditions. Correlation values between plant height vs. pods plant−1, plant height vs. leaf area, plant height vs. days to flowering, plant height vs. pod length, plant height vs. grains pod−1 and plant height vs. yield plant−1 were determined and exhibited in this context. The aims of this experiment were to explore the suitable area and congenial environment for better crop productivity amongst those two locations.
