Nutrigenomics has an undoubtedly immeasurable potential for revamping human health. It has become an important regimen due to its consequential role in medical and nutritional sciences. It is an interdisciplinary science that amalgamates the information from physiology, pathology, genetics, molecular biology, and nutrition to establish the effects of ingested nutrients on expression and regulation of genes. The ultimate aim of nutrigenomics is to ascertain the nutritional requirement of an individual in accordance with genetic makeup. Moreover, it aims to purvey treatment in the management of certain ailments having a dietary role based on individual’s genomic profile. Therefore, vast research in the field of nutritional genomics is a dire need to make people aware regarding their health and diet relationship. Here, we have given an overview of nutrigenomics coupled with novel technologies to produce utilitarian information for health professionals and researchers by divulging certain properties that interfere with the genomic machinery.
Aim: To characterize kale (Brassica oleracea group Acephala) germplasm well adapted for July to December cropping season in Kashmir valley for suitability for year round cultivation with respect to leaf yield (t/ha). Study Design: Random Complete Block Design with two replications. Place and duration of study: The study was done in Vegetable Experimental Field of ICAR-Central Institute of Temperate Horticulture, Srinagar, Jammu and Kashmir, India from 2017-18 to 2018-19. Methodology: The germplasm comprising breeding lines and landraces as checks was sown and then transplanted at different times of the year to evaluate for leaf yield potential at edible maturity stage. The final yield for each genotype was calculated by summing up all pickings. Critical differences among genotypes for total leaf yield were calculated from ANOVA using OPSTAT online tool for one factor analysis. Results: Considering the average performance of two years in terms of leaf yield in tone per hectare, NW-Saag-1 (24.77, 25.08 and 25.01), CITH-KC-16 (28.79, 26.74 and 11.20) and CITH-KC-18 (24.25, 24.14 and 11.91) were found to yield significantly better than local checks Khanyari (7.77, 8.47 and 21.31) and GM Dari (10.36, 15.98 and 9.65) when transplanted in May, June and July, respectively. Months of April, May, June, July and August were most conducive for normal nursery production followed by May to September transplanting to get economical yields. January sowing of selected genotypes in polyhouse along with added protection from polysheet resulted in vigorous and healthy seedlings. Their transplanting in the second fortnight of March resulted only in short vegetative phase of the crop followed by bolting and seed production. However, this approach came out as an opportunity to produce seed in 7 months (January to July) compared to 1 year normally taken in farmer adopted seed production method. Conclusion: NW-Saag-1, CITH-KC-16 and CITH-KC-18 lines yielded significantly higher than local landrace kales for offseason cultivation and seed-to-seed technique of seed production is an economic and short method of kale seed production in Kashmir valley.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
