Application of advanced backcross QTL analysis in crop improvement

  Domestication of crops is widely believed to be accompanied by a bottleneck that greatly reduces genetic diversity. This narrowing of genetic diversity restricts crop plant improvement by limiting the range of valuable traits available for use in modern plant breeding. Wild species are a broad resource to widen the germplasm and improve the traits in crop cultivars. However, genetic variation between species...

Development and use of microsatellites markers for genetic variation analysis, in the Namibian germplasm, both within and between populations of marama bean (Tylosema esculentum)

  Tylosema esculentum (marama) has long been identified as a candidate crop for arid and semi-arid environments due to its success in these environments and the high nutritional value of the seed. Molecular markers are essential for the assessment of the levels of genetic variation present within and between populations of marama as well for future marker-assisted breeding efforts. Microsatellites were...

Evaluation of head yield and participatory selection of horticultural characters in cabbage (Brassica oleraceae var. capitata)

  Cabbage is an important leafy vegetable in sub-Saharan Africa, yet breeding and seed production activities take place in Europe and Asia. Participatory evaluation of varieties alongside head yield was carried out to select preferred varieties. Field experiments were conducted during the 2008 long rainy season and the 2008/09 short rainy season at AVRDC–The World Vegetable Center, Regional Center for...

Development of a fast and reliable ozone screening method in rice (Oryza sativa L.)

  A rapid and reliable screening method for rice ozone tolerance was developed to enhance evaluation technique in determining the reaction of tolerant and susceptible genotypes at the early stage of growth. Plant growth parameters were measured to evaluate ozone effects on the growth of seedlings which can be later used as criteria for ozone tolerance. Plants were subjected to 0.3 and 1 ppm ozone using 15 and...

Comparative effects of water deficit on Medicago laciniata and Medicago truncatula lines sampled from sympatric populations

  We evaluated the responses to water deficit of twelve lines of Medicago laciniataand Medicago truncatula including eight lines from four Tunisian sympatric populations of both species, and four references lines of M. truncatula. They were exposed to two water treatments, well irrigated and drought-stress (33% of field capacity) for a period of 45 days. At harvest, we measured five...
