GENETIC DIVERGENCE IN TRITICALE

Published on

The genetic divergence among25 elite lines of triticale alongwith Sonalikacultivarof bread
wheat was assessed employing Mahalanobis' D2 analysis based on 16 characters. Four
dusters were formed. Cluster I was the largest with 23 lines. The remaining three clusters
with one line each were highly diverse from one another. The spike length, days to heading
and maturity, plant height, spikes per 0.5 m2, grain hardiness, tillers per plant and grain
yield had sizeableindividualcontribution towards geneticdivergence among lines. Results
revealed the narrow genetic base among elite lines in triticale. The need for widening the
genetic base by integrating wheat germplasm into triticale crossing programme has been
emphasized.
 

Keywords: Cluster, D2 statistic, genetic diversity, triticale.
