Twenty five tomato (Solanum lycopersicum L.) genotypes were subjected to genetic diversity analysis using twenty SSR markers. Out of 20 markers used, 14 SSRs were polymorphic and a total numbers of 22 SSR alleles were generated by 14 SSR markers, out of which 19 were polymorphic and 3 were monomorphic, with an average of 1.57 alleles per locus. The range of amplified products was 100-400bp approximately. Jaccard’s similarity coefficient varied from 0.65 between germplasm EC519821 and CO-3 to a maximum of 1.0 between genotypes EC519769 and DARL-66, with an average value of 0.83. Cluster analysis based on Jaccard’s similarity coefficient using the unweighted pair-group method with arithmetic mean (UPGMA) revealed 2 distinct clusters, A and B, comprising 1 and 24 genotypes respectively and at 75 and 78 per cent similarity, respectively. The genotypes which showed similar morphological and genetic trends were grouped more or less together in both these cases were a few. Cluster A comprised most diverse germplasm (EC519821)belongs to pimpinellifolium wild species with similarity coefficient 0.65% and differentiated with other cultivated species.Cherry Tomato and Cherry-2 were trends in similar cluster similar with approximately 96% similarity.SSR markers were able in in differentiating the genotypes based on morphologically and genotypically.However, the grouping of 25 genotypes were independently of geographic distribution.The genetic distance information found in this study might be helpful to breeder for planning among these genotypes.

Milk and milk products comprise essential nutrients for all age groups. Hence ensuring the quality and safety of dairy products offered to the consumers is mandatory objective of the dairy industry. India is the first ranker in milk production in the world (18.5%) with a total annual production of 146.3 million tonnes and per capita availability of 322 g/day India stands first in the milk production. The total quantity of dairy products exported from India in the year 2016–17 is 39397.61 million tonnes with value 91044.07 lakhs. Antibiotics are mainly employed for chemotherapeutic, prophylactic purposes and also used as feed additives to promote growth and improve feed efficiency. However, antibiotic residues in animal products may occur, when administration of drug in extra label fashion and not following of withholding period after treatment. The major public health significances of antimicrobial residues include the development of antimicrobial drug resistance, hypersensitivity reaction, carcinogenicity, mutagenicity, teratogenicity, bone marrow depression, and disruption of normal intestinal flora. The aim of this review is to present indiscriminate use of antimicrobials in animals resulting in occurrence of residues in milk and milk products and associated harmful health effects in humans requires control measures to ensure consumer protection.

Maize Plants grown in subtropical and temperate regions are often subjected to moisture stress. the wild progenitors of the crop species are the important source of genes of various abiotic and biotic stress tolerance. teosinte (Z. mays ssp. parviglumis), the progenitor of maize possesses several important genes of agronomic importance, majority of which were lost during the process of domestication. In the present investigation, 203 modern maize BC₁F₂ introgressed lines (encoded as am-1 to am-203) were developed and evaluated under irrigated and moisture stressed environments. In order to introduce the genes of agronomic importance from the progenitor teosinte to modern maize, DI-103 inbred were crossed with teosinte. the present study involved evaluation of 203 lines (encoded as am-1 to am-203). these lines were grown in a single row in two environmental conditions i.e. irrigated and stress condition during Rabi 2016–17 for the phenotyping of morpho-physiological traits viz., anthesis silking interval (ASI), leaf rolling, leaf firing, canopy temperature depression (CTD), chlorophyll content, ear length, ear diameter, kernel rows/ear, kernels/row, tip filling, grain filling, grain yield per plants (g), and 1000-kernel weight and drought tolerance index, stress tolerance index, yield index associated with drought tolerance. Overall sum of rank scores over thirteen traits associated with drought tolerance revealed that am-39 was the most drought tolerant line among all the 203 lines under study with a total score of one hundred eight, followed by am-64, am-16, am-42, and am-102, whereas, am-116 was the most susceptible, with the least score of thirty-four.
