Performance of Winter-Sown Chickpea Breeding Lines with Contrasting Levels of Resistance to Ascochyta Blight

Multi-environment field testing of chickpea accessions winter sown in Southern Spain showed that environmental effects on yield were more important than genotypic and GEI. The most detrimental factor grain was ascochyta blight infection. We did not find a significant effect low temperatures the environments studied, probably due to mild winters area. On contrary, we found high at reproductive stage, particularly with numbers days Tmax >30 °C. larger infection as included previously selected for their levels resistance or susceptibility. Biplots based WAASB/productivity ratio highlighted AS19, AS30, AS23, AS26, AS18 best productivity stability yield, matching those lower MTSI index also identified these region.
