Phenotypic and micronutrients data of Sorghum RIL populations trial during 2012-13 postrainy season at VNMKV, Parbhani

The low grain iron and zinc densities are well documented problems in food crops, affecting crop nutritional quality especially in cereals. Sorghum is a major source of energy and micronutrients for majority of population in Africa and central India. The database includes the investigation was carried out principally to study the variation for grain iron (Fe) and zinc (Zn) concentration, G × E interaction and association between these two traits and agronomic traits in RIL (Recombinant Inbred Line) population consisting of 309 individuals of generation developed using two contrasting parents 296 B and PVK 801 along with parents (296 B and PVK 801). The experiment was conducted during postrainy 2012-2013 season in Vasantrao Naik Marathwada Krishi Vidhyapeeth (VNMKV)-Parbhani located at an altitude of 357 m above mean sea level with latitude of 18.45◦N and longitude of 76.13◦E to obtain best quality grain for assessing grain Fe and Zn concentration. The trial was conducted using Alpha Lattice design with three replications. Seeds of each entry were distributed equally to seed packets, representing number of rows of each plot size; and then randomized plot numbers were assigned to each plot seed packets and arranged according to planned field layout. Each entry was planted in two rows of 2 m length with a spacing of 75 cm between rows and 15 cm between plants in a row. The data on parameters like days to 50% flowering, plant height (cm), 100 seed weight (g), Fe (mg kg-1), Zn (mg kg-1), grain weight per meter square were recorded. The RIL population study showed good variability and high heritabilities for Fe and Zn and other traits studied indicating its suitability to map QTL for iron and zinc. <br> <br> <b> <a href="https://drive.google.com/open?id=1ZcU4Zfg05ahZHNwSCGWjw2If-K8rI_2G&usp=sharing">Experiment location on Google Map</a> </b> <br> <br>
