Stripe rust (yellow rust), caused by Puccinia striiformis f. sp. tritici is one of the most damaging diseases of wheat in Pakistan. Lack of durable resistance in local wheat varieties is the main reason for stripe rust epidemic which could limit yields. The use of genetically resistant wheat varieties is the most economic way of controlling the disease. Evaluation of 135 advance wheat lines for...

turfgrasses are usually important groundcover plants in many landscapes. they occupy the lowest surface of the landscape, close to pollutant particles. so, they can be an attractive option for environmental remediation. today, high concentrations of hazardous chemicals such as lead are among the most serious environmental problems. in vitro selection of turfgrass accumulator or tolerant of toxi...

Genetic diversity among plant species offers prospects for improving the plant characteristics. Its assessment is necessary to help tackle the threats of environmental fluctuations and for the effective exploitation of genetic resources in breeding programmes. Although wheat is one of the most thoroughly studied crops in terms of genetic polymorphism studies, phylogenetic affinities of Indian a...

genetic diversity is the basis success of improving the quality and quantity of crops. recognizing of genetic diversity and genetic potential of each plant species in plant breeding is necessary. in this study genetic diversity of 30 lentil samples belonging to collection of the college of agriculture of krage were evaluated using rapd molecular markers. rapd products were scored for presence (...

robust information of genetic diversity among bt cotton genotypes is still lacking and availability of several marker systems has prompted us to compare their utility for the detection of genetic diversity. here, we report the comparative efficiency of morphological and molecular markers (est-ssrs and issrs) in determining the genetic diversity among 30 pakistani bt cotton genotypes. three diff...

Tall fescue (Festuca arundinacea Schreb.) is an important cool-season perennial grass species used as forage and turf, and in conservation plantings. There are three morphotypes in hexaploid tall fescue: Continental, Mediterranean and Rhizomatous. This study was conducted to develop morphotype-specific molecular markers to distinguish Continental and Mediterranean tall fescues, and establish th...

The awn is a long needle-like structure formed at the tip of the lemma in the florets of some grass species. It plays a role in seed dispersal and protection against animals, and can contribute to the photosynthetic activity of spikes. Three main dominant inhibitors of awn development (Hd, B1 and B2) are known in hexaploid wheat, but the causal genes have not been cloned yet and a genetic assoc...
