The present study was carried out with the objective of assessing the losses caused by pulse beetle (Callosobruchus spp.) during storage of chickpea grains in various storage structures. It was found that, still farmers are using traditional storage structures (earthen pots, earthen pots + sand, jute bags). Chickpea grain samples (500g each) were collected during August, September and October from different storage structures (metal bins, plastic bags, gunny bags, earthen pots and earthen pots + sand) in 15 villages of Rewari, Hisar and Mahendergarh district in the year 2017 and 2018. The results of analysed samples revealed that the highest infestation was observed in Rewari followed by Hisar and Mahendergarh district. It was found that maximum number of farmers were using metal bins (51.45, 40.11%) followed by gunny bugs (31.79, 31.64%), plastic bags (16.76, 15.82%), Earthen pots (6.51, 7.91%) and Earthen pots + sand (2.35, 4.52%) to store the chickpea grains in 2017 and 2018, respectively. Out of total samples infested with bruchid, 70.91 & 53.63 per cent gunny bag samples were found infested followed by plastic bags (48.28 & 20.29%), metal bins (11.24 & 15.94%) and earthen pots (9.80 & 10.14%) in both the years. There was no infestation of pulse beetle observed in those samples which were stored in earthen pots along with sand. Higher moisture percentage in the grain and infestation of pulse beetle was observed in the month of September followed by October in comparison to August month. Among the storage structures in frequent use, metal bins were found to have less qualitative and quantitative losses of seed/grains.

Background: In white jute, very limited success has been reported by researchers to break yield plateau due to the narrow genetic base of the genetic material available with the breeders. Evaluation of agronomic traits and information about genetic variance in the breeding population is essential for selection and in planning crosses to enhance the productivity and diversity in cultivars. Yield character components are inherited and each one accounts for variations in yield, hence interrelated with each other. The current investigation was done to measure the genetic variability and genetic diversity of white jute genotypes for characters and interrelationship that contribute to yield and fibre quality.Methods: In the present study, fifty-two white jute (C. capsularis L.) genotypes were assessed during the Pre-Kharif season of 2017 at the Teaching Farm of Bidhan Chandra Krishi Viswavidyalaya, Mandouri, Nadia, West Bengal. Plants were raised in randomized block design with three replications. Statistical analysis was done for the estimation of ANOVA variability, correlation and path analysis and genetic divergence.Result: Plant height and bark thickness with high heritability and high genetic advance were identified as important selection parameters. Plant height, bark thickness and green weight per plant had a significantly high positive correlation with dry fibre weight per plant both at genotypic and phenotypic levels. Plant height had the highest contribution toward the dry fibre weight followed by bark thickness. Genotypes were grouped into 13 clusters and cluster I had the highest number of 23 genotypes. The inter-cluster distance was found maximum between cluster I and cluster VI. Cluster XI recorded the highest mean for the plant height. Ten genotypes identified from different clusters in this study can be incorporated as donors in hybridization to combine both yield and improved fibre quality.
