Novel Genetic Resources in the Genus Vigna Unveiled from Gene Bank Accessions

The genus Vigna (Fabaceae) consists of five subgenera, and includes more than 100 wild species. In Vigna, 10 crops have been domesticated from three subgenera, Vigna, Plectrotropis, and Ceratotropis. The habitats of wild Vigna species are so diverse that their genomes could harbor various genes responsible for environmental stress adaptation, which could lead to innovations in agriculture. Sinc...

Genetic Diversity of the Pm3 Powdery Mildew Resistance Alleles in Wheat Gene Bank Accessions as Assessed by Molecular Markers

Genetic resources of crop plants are essential for crop breeding. They are conserved in gene banks in form of a large numbers of accessions. These accessions harbor allelic variants of agronomically important genes and molecular tools allow a rapid assessment of this allelic diversity. Here, we have screened a collection of 1005 wheat gene bank accessions for powdery mildew resistance and a mol...

Determination of levels of Striga germination Stimulants for maize gene bank accessions and elite inbred lines

Parasitism by Striga hermonthica (Del) Benth is a severe constraint in maizeproduction in sub-Saharan Africa. Varying levels of tolerance to Striga attack havebeen identified and exploited in breeding programs of several crops. However, thelevel and stability of the tolerance is generally unacceptable in field-practice. Onlylimited exploration has been undertaken among the farmers’ landraces to...

Genetic variability in accessions of the acerola germplasm bank of Universidade Federal Rural de Pernambuco, Brazil.

Brazil is the world's largest producer of acerola, Malpighia emarginata (Malpighiaceae); the Northeast is responsible for 60% of the national production. The culture of acerola in Brazil has great genetic variability; plantings have high phenotypic diversity and are not very productive, often originating from propagation by seed. We evaluated the genetic diversity of 42 accessions from the Acer...

PLANT GENETIC RESOURCES Testcross Performance of Semiexotic Inbred Lines Derived from Latin American Maize Accessions

from Oh43 (Darrah and Zuber, 1986). Smith (1988) reported that a small number of lines, including B73, Tropical maize (Zea mays L.) represents the most diverse readily A632, Mo17, and Oh43, were the major contributors to available source of germplasm to broaden the limited genetic base of commercial U.S. maize hybrids. Subsequently, Smith et temperate maize in the USA. One objective of this stu...
