Other claims from this paper (14)
- Intervention effect Drought stress reduced chickpea grain yield by 23%.
- Observation Mean carbon isotope discrimination was low in chickpea accessions under drought stress.
- Observation The range of genetic variation in carbon isotope discrimination was high under drought stress.
- Association High carbon isotope discrimination accessions were early in flowering (40-50 days).
- Association High carbon isotope discrimination accessions had high seed yields.
- Association High carbon isotope discrimination accessions had high harvest index.
- Association Carbon isotope discrimination was positively correlated with seed yield under drought stress in both years.
- Association The positive correlation of carbon isotope discrimination with seed yield was found only in 2008-09 under optimal irrigation.
- Association The positive association of carbon isotope discrimination with seed yield was very close with harvest index.
- Association Among the yield components, carbon isotope discrimination was closely associated with pod numbers per unit area and seed size under drought stress.
- Observation Carbon isotope discrimination showed no direct association with grain yield in path analysis.
- Association Carbon isotope discrimination had an indirect negative association with grain yield through shoot biomass at maturity.
- Observation Carbon isotope discrimination had a close positive association with grain yield through harvest index.
- Association The closest association of harvest index or shoot biomass was in the maturity group of accessions under optimum terminal drought stress.
