| dc.description.abstract | The objective of national oat breeding program is to develop the oat varieties with high yielding,resistant to diseases, drought, cold, and heat stresses and suitable for different usages (food, feed, and forage).To achieve that goal, a total of 284 (232 lines + 52 checks) oat genotypes were tested under rain-fed conditionsat the yield, advanced yield, and elite yield trials conducted between 2008 and 2012. During the consecutiveoat breeding cycles, genotypes with high yielding and acceptable quality were promoted. Among the qualitytraits, protein content (PC), oil content (OC), and test weight (TW) were preferred as selection criteria. Heritability (H) and correlation coefficients were estimated for the GY and quality characteristics of thegenotypes tested. While the H for GY was low (0.38), Hs for quality traits (PC, OC, and TW) were medium (0.66,0.68, and 0.57, respectively). As for the correlations between the traits of interest, the statistically significantpositive relationships were observed between GY and OC, GY and TW, and OC and TW. In contrast, statisticallysignificant negative associations were measured between GY and PC, PC and OC, and PC and TW. Negativerelationships and low-medium H values calculated for the traits studied appear to be the most critical obstaclesfor national oat breeding program. To tackle these obstacles, the parents, i.e., gene pool, used in the oatcrossing block should be characterized as soon as possible and enriched with introducing new exoticgermplasm. We believe that by doing so, we can develop high yielding and high-quality oat varieties. | |
