The Eruca sativa (Taramira) germplasm, comprising 102 accessions was evaluated for total seed storage proteins via sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The accessions were collected from different ecological areas of Pakistan. Total seed storage proteins were electrophoretically separated on 12.5 to 15.0% polyacrylamide gels. A total of 17 protein bands were det...

Understanding of genetic diversity and linkage disequilibrium (LD) decay in diverse maize germplasm is fundamentally important for maize improvement. A total of 287 tropical and 160 temperate inbred lines were genotyped with 1943 single nucleotide polymorphism (SNP) markers of high quality and compared for genetic diversity and LD decay using the SNPs and their haplotypes developed from genic a...

Germplasm architecture refers to how favorable alleles for a given trait are distributed across the genome in a germplasm collection. Our objective was to assess germplasm architecture for quantitative traits among US maize ( L.) inbreds. A total of 271 inbreds were genotyped at 28,626 single nucleotide polymorphism (SNP) loci and phenotyped for anthesis date, plant height, starch and protein c...

To optimize the exploitation of plant genetic resources for improvement of oilseed crops in Pakistan, seed quality characterization of germplasm of rapeseed is being executed at Nuclear Institute for Food and Agriculture (NIFA), Peshawar. The aim of this study was to determine the feasibility of using Near Infrared Spectroscopy (NIRS) to identify seed quality traits of oilseed rape germplasm. S...

This study was conducted to determine the Phytophthora rot resistance of 514 accessions of watermelon germplasm, Citrullus lanatus var lanatus. About 46% of the 514 accessions tested were collections from Uzbekistan, Turkey, China, U.S.A., and Ukraine. Phytophthora capsici was inoculated to 45-day-old watermelon seedlings by drenching with 5 ml of sporangial suspension (10(6) sporangia/ml). At ...

Knowledge of the inheritance of C-glycosyl flavone synthesis in maize (Zea mays L.) silk tissues has been acquired through detailed genetic studies involving primarily germplasm from the Corn Belt Dent race. To test the robustness of this genetic knowledge, we examined C-glycosyl flavone synthesis in a genetically distinct germplasm pool, popcorn. C-glycosyl flavone profiles and levels and the ...

Genetic resources provide basic material for selection and improvement through breeding to ensure food security needs of the world’s rapidly rising population. Conservation and utilization of plant genetic resources are important components of ex-situ collections. Management of ex-situ collections requires creative and adaptive decisions tailored to operating conditions that are specific and co...

We announce here the first complete chloroplast genome sequence of the tropical japonica rice, along with its genome structure and functional annotation. The plant was collected from Indonesia and deposited as a germplasm accession of the International Rice GenBank Collection (IRGC 66630) at the International Rice Research Institute (IRRI). This genome provides valuable data for the future util...

Root traits influence the amount of water and nutrient absorption, and are important for maintaining crop yield under drought conditions. The objectives of this research were to characterize variability of root traits among spring wheat genotypes and determine whether root traits are related to shoot traits (plant height, tiller number per plant, shoot dry weight, and coleoptile length), region...
