“…NC 2 had a superior profile and was popular in the limited seed market of its time, but Florigiant was the first cultivar documented to predomi- nate across the entire Virginia-Carolina peanut produc tion region (Isleib and Wynne, 1992). Florigiant com bined excellent pod characteristics desired by shellers with high yield potential desired by growers, but its flavor attributes were inferior.…”

“…Cultivar development also introduced many desirable characteristics for peanut farming and industry such as integrated multiple disease and pest resistances, improved drought tolerance, and improved seed oil composition, etc. (Isleib, et al, 2001;Chu, et al, 2011). Three main approaches have been applied in crop improvement: 1) artificial hybridization commonly known as crossing, 2) mutagenesis by chemicals or radiation, and 3) genetic transformation.…”

“…Contrastingly, the diploid wild-type ancestors are inherently heterogeneous and preferably selected for cumulating stress resistant genes during adaptation to severe environments Subramania et al 2000;Gimenes et al 2002). The minimal level of variation in cultivated peanut has been accredited to three reasons or to combinations of those: (1) obstructions to gene flow from associated diploid species to domesticated peanut as a result of the polyploidization issue (Young et al 1996); (2) fresh polyploidization, from one or a small number of individual(s) of each diploid parental species, combined with self-pollination ; or (3) utilization of few leading breeding lines and few exotic germplasms in breeding programs, ensuing in a limited genetic base (Isleib and Wynne 1992). On the other hand, selection of genetically diverse parents, which is expected to develop superior and desirable segregants following crossing, enables the expansion of genetic base and development of superior genotypes ).…”
