gene pool of lettuce comprises germplasm that is fully interfertile with L. sativa , including the wild species L. serriola and several L. serriola -like species. Lactuca saligna and L. virosa represent the secondary and tertiary gene pools

genes provide resistance to all races of the pathogen maintained at BARC ( Pastor-Corrales et al., 2007 ). Within the cropping systems of eastern Africa, common bean genotypes from Andean and Middle America gene pools are grown, although the distribution

absence of the virus was determined using a positive control CYSDV plasmid; samples with cycle threshold values less than 35 cycles were considered positive. Statistics. Genotypes were split into gene pools based on their compatibility with C

diversity has been an impediment to the genetic improvement of cucumber in several commercially important market classes ( Staub et al., 2008 ). Harlan and de Wet (1971) introduced the concept of gene pools (primary, secondary, and tertiary) to explain
