Study on genotypic and phenotypic correlations in triticale indicated that spike length, harvest index, and grains per spike were positively associated with grain yield. Path-eoefficient analysis revealed that spike length, flag leaf area, days to heading, spike lets per spike and 1000-grain weight were the major charaders influencing grain yield directly and indirectly. The results suggested that spike length could be taken as the most reliable and effective selection criterion for yield improvement.
