Competition Indicator in Alfalfa Populations Following Recurrent Selection to Glyphosate Tolerance

Evaluation and selection for salinity stress tolerance in Iranian promising alfalfa (Medicago sativa L.) ecotypes

To improve salinity stress tolerance in Iranian promising alfalfa ecotypes, including Shorkat, Gharghologh, Gharaghozloo, Rehnani, Roodasht Isfahan and Gavkhooni, a recurrent selection scheme was carried out at roodasht and kabootarabad field stations, Isfahan, Iran, during 2012-2017 growing seasons. Six Iranian promising alfalfa ecotypes were planted in the autumn of 2012 and irrigated with sa...

Efficiency of Indirect Selection to Improve Yield and Drought Tolerance in Populations Derived from Inter-Specific Hybridization of Soft Flower

The use of appropriate selection methods are important to increase yield in breeding programs. Utilization of selection indices is one of the most effective method for selection of superior genotypes to improve the complex traits such as seed yield. In order to evaluate the efficiency of different selection methods, 63 families of two F3 populations derived from inter-specific hybridization of ...

Glyphosate-tolerant alfalfa is compositionally equivalent to conventional alfalfa (Medicago sativa L.).

Glyphosate-tolerant alfalfa (GTA) was developed to withstand over-the-top applications of glyphosate, the active ingredient in Roundup agricultural herbicides. As a part of the safety assessment, GTA (designated J101 x J163) was grown under controlled field conditions at geographically diverse locations within the United States during the 2001 and 2003 field seasons along with control and other...

Response of typha latiffolia to cutting competition and glyphosate under field conditions

Glyphosate Tolerance in Transgenic Canola by a Modified Glyphosate Oxidoreductase (gox) Gene

The engineering of transgenic canola (Brassica napus L. ) to make tolerance to the broad-spectrum herbicide, glyphosate, is one of the most effective approaches for weed management. Glyphosate inhibits the enzyme EPSPS (5-enolpyruvylshikimate-3-phosphate synthase) enzyme which functions in the shikimate pathway and has a key role in biosynthesis of aromatic amino acids required for survival of ...
