Allelic data revealing interrelatedness in rice species (Oryza sativa, Oryza glaberrima, Oryza barthii) and the interspecific hybrids (NERICA)

  The current level of genome coverage provided by microsatellite markers in rice is sufficient for DNA fingerprinting, providing Information on diversity and population structure which is expected to assist plant breeders by providing a more rational basis for expanding the gene pool and for identifying material that harbours alleles of value for plant improvement. Allelic data from the species studied...

Salinity effect on plant growth at the seedling stage of durum wheat (Triticum durum Desf.)

  Soil salinity is a serious threat in many parts of the world in general and of Tunisia in particular, which negatively affects plant production. In this experiment, response of durum wheat to salinity in seven genotypes namely; four local cultivars (Azizi, Jenah Khotifa, Hmira and Swebâa Eljia), two improved varieties (Karim and Om Rabia) and an algerian cultivar (Oued Zeneti)] to salinity (0 and 100 mM...

Rapid and high-precision marker assisted backcrossing to introgress the SUB1 QTL into the Vietnamese elite rice variety

    Submergence stress regularly influences about 15 million hectares of rice growing areas in South and Southeast Asia. Vietnam is one of the most vulnerable countries affected by submergence stress in Asia. Submergence caused by typhoons and floods is one of the major reasons for rice production losses in this country. A majorquantitative trait locus (QTL) on chromosome...
