in order to investigate genetic variation of traits related to seed yield, 41 genotypes from 14 wild and cultivated species were evaluated according to a randomized complete block design with three replications in isfahan university of technology research farm. the genotypes were significantly different for all of the studied traits indicating existence of considerable genetic variation in this...

Q. Zhang and R.A. Wing (eds.), Genetics and Genomics of Rice, Plant Genetics and Genomics: Crops and Models 5, DOI 10.1007/978-1-4614-7903-1_2, © Springer Science+Business Media New York 2014 The wild species of the genus Oryza serve as a virtually untapped reservoir of genetic diversity that can be used to improve the world’s most important food crop—rice. The genus is composed of two domestic...

Our ability to manage gene flow within traditional agroecosystems and their repercussions requires understanding the biology of crops, including farming practices' role in crop ecology. That these practices' effects on crop population genetics have not been quantified bespeaks lack of an appropriate analytical framework. We use a model that construes seed-management practices as part of a crop'...

Landscape degradation is a major threat to global biodiversity that being further exacerbated by climate change. Halting or reversing decline using seed-based restoration requires tons of seed, most which sourced from wild populations. However, in regions where urgent, seed sources are often fragmented, declining and producing with low genetic diversity. Seed production areas (SPAs) can help re...

Common wild rice (Oryza rufipogon Griff.) is an important germplasm for rice breeding, which contains many resistance genes. Re-sequencing provides an unprecedented opportunity to explore the abundant useful genes at whole genome level. Here, we identified the nucleotide-binding site leucine-rich repeat (NBS-LRR) encoding genes by re-sequencing of two wild rice lines (i.e. Huaye 1 and Huaye 2) ...

Ten germplasm of Desi and Kabuli chickpea namely BGM-568, JKG-5303, KKG-306, BG-2083, JSC-61, NDG-5-21, Udai, NDG-54, KWR108, and BG-256 were collected from department of GPB of this university and taken in present research work. After harvesting the seeds of all the germplasm were collected separately and used for analysis of some physical, protein fractionation and amino acid composition. The...

Recurrent drought and Striga hermonthica (Del.) Benth parasitism constrains maize production in sub-Saharan Africa (SSA). Transfer of resistance genes from wild relatives can improve to tropical maize. The objectives this study were (i) determine the combining ability 12 extra-early yellow inbreds derived Zea diploperennis germplasm; (ii) classify into heterotic groups using grouping based on g...

Wild potato germplasm serves as a natural pool of agronomically valuable traits for breeding, such resistance to pathogens and abiotic stresses, quality, consumer-oriented traits. The introgression these into cultivated is hampered by the different kinds incompatibility linkages between desirable undesirable features in hybrid progeny. trait donor improvement via correction negative characteris...

An expected use case of plant phenotype ontologies will be the identification of germplasm containing particular traits of interest. If phenotype data from experiments is annotated using ontologies, it makes sense to include annotations to that germplasm source. A lack of standardized data formatting reduces the utility of these data. Standardizing germplasm data, including links to germplasm d...
