Indian flying corps and Israel Aerospace Industries (IAI) forged long standing military ties, Israel aviation enterprises keeping up their strong position as best-in-class UAV manufacturers for both civilian and military use and supplying the Indian military with advanced UAV frameworks. IAI has provided IAF with a sum of 176 Israel-made automatons including 108 IAI Searchers and 68 unarmed Heron-1 airships for observation and surveillance missions including an armada of IAI Harpy rambles. With the expanding request of India's military associations, for example, the DRDO, Aeronautical Development Establishment (ADE), the National Aerospace Laboratories (NAL), Hindustan Aeronautics Limited (HAL) have been creating UAVs with ISR, focusing on, and weapon direction abilities. The first trip of the Rustom-2 model on 16 November 2016 was a turning point for India. This work shows the correlation of the Indian and Israeli UAVs created depending on their main capacities and execution qualities.

The study on diversity of pummelo (Citrus grandis Osbeck) was undertaken to assess the variability of collected genotypes from fourteen district of West Bengal in the year of 2016-17. One hundred twenty four genotypes were selected based on assessment of traits provided by the farmers (fruit bearing frequency, maturity, fruit yield) as well as in-situ observation of trees and fruit"s characters with an objective for selecting genotypes from divergent clusters and utilizing them in a hybridization programme is likely to produce desirable segregates in subsequent generations that may lead to desirable improvement in pummelo for quality traits. The analytical works were conducted in the laboratory of Fruits Science of Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal. The data obtained were analyzed by different method like-Hierarchical cluster analysis, descriptive analysis, Principal Component Analysis and Biplot. The genotypes were grouped based on ten core quantitative characters of fruits into fifty six clusters. It is observed that all the clusters were distant each other and among them cluster 49 was the largest one consisting of 55 pummelo genotypes followed by cluster 43 and cluster 52 with three genotypes. The co-efficient of variation was high (>20) for five measured or quantitative characters like fruit weight, fruit rind thickness, seed weight, acidity, and ascorbic acid. Principal component analysis of ten core quantitative characters of pummelo showed four components with cumulative variance of 69.357 per cent. Highly loaded characters (>0.5), obtained from PCA for quantitative variables in the first two components, were fruit weight, fruit diameter, fruit length, rind thickness, seed number and seed weight. So, considering all the characters it may be concluded that NPC2,
