| Özet |
| A barley drought tolerance Quantitatif Trait Locus (QTL) on chromosome 2 was transferred from tolerant cultivar ‘Tadmor’ to susceptible ‘Baronesse’ and ‘Aydanhanım’. Effects of this QTL on drought tolerance and other traits were studied using near‐isogenic lines under controlled environments and field trials for two years. This QTL resulted in 5.0% and 9.1% improvement in leaf relative water content of ‘Baronesse’ and ‘Aydanhanım’ cultivars, respectively, under controlled environments. The QTL accelerated heading and maturity by 2.5 days in ‘Baronesse’ and by 5–6 days in ‘Aydanhanım’. It was associated with shorter stature and more ears. This QTL region increased grain yields by 1.1 and 0.6 t/ha in ‘Baronesse’ and ‘Aydanhanım’, respectively, mainly by increasing the number of tillers. There were previous reports related to yield promoting effects of this region harbouring flowering locus eps2 (barley HvCEN … |
