dc.description.abstractWith the aim of developing chickea cultivars including blight resistance and large seeds a crossing program between 5 tesistant adrzncec{ lines v'ith medium-large seeds and defferent sources of resistance were inidated in year 2005. Those advanced lines were originally derived from crosses between resistant accessions from ICARDA and the Spanish large seeded (around 0.50 g per seed) and susceptible local cultivar 'Blanco Lechoso'. A F2, population with a total of 909 plants was obtained joining F2-derived fiom all possible crosses between the 5 advanced lines. Early generation testing method of F2-derived lines was employed for large seed selection until F2:5 families. The best individuals from the best F2:5 families were selected and advanced selecting for large seeds until F5:8. Finally, in 2011/2012 agronomic season, 30 F5:8 advances lines were sown following a randomized block design with two repetitions and parents as control. Eleven lines with larger seed size than the best parent (0.44 g per seed) were selected (ranking from 0.49 g to 0.57 g per seed).These results suggestt that transgressive segregation is present in chickpea for seed size.In order to test the presence of QTLs for ascochyta blight in the advance lines, allele-specific markers for QTL ar1 (CaETR) and QTLar2 (SCY17 590) employed. Both QTLs were present in all selected lines.-
