Advanced study of new seedless grapes obtained from crossing among seeded and seedless grapes

In this research work, seven seeded grape cultivars were crossed with four Iranian seedless grapes to produce new superior seedless grapes as a table grape as well as raisin. Crosses were resulted in 1400 progenies in which 322 progenies in 2010 and 419 progenies in 2011 were evaluated and compared with their own seedless parents as well as cultivars such as Perlette and Flame seedless. Progenies were divided into four grapes of seedless, semi seedless, semi seeded and seeded ones. Some seedless progenies had large berries with good attachment of berries to bunch stem and convenient berry density. Among all studied genotypes; B182,N191, J107,B180 , K79, C88, L55, A170, M90, L196 & L207 were completely seedless in which B182 had largest berries(2.2gr). Some other genotypes such as J113, M91, S66, I116, A201, C95, J69, E159 & N165 were recorded as semi seedless ones in which J113 had largest berries (2.9gr).
