Abstract/Description: | Salinity of land and water is one of the major constraints in agricultural crop production especially for wheat in India. Genetically variable base population along with reliable screening technique is prerequisite for developing high yielding and salt tolerant wheat cultivar. The present study was undertaken in partially reclaimed sodic field as well as micro-plots to estimate genetic variability, trait association and identification of key traits for salt tolerance coupled with high yield in wheat. Fifty elite wheat germplasm lines obtained from CIMMYT’s 19th SAWYT trial were used in the study. Highly significant variation for various traits signifies that genotypes can be improved through breeding and selection. Eight superior genotypes were identified having yield advantage of 5 to 13 per cent compared with check KRL 210 coupled with good amount of salt tolerance. Biomass had significant relationship with yield while test weight was associated with salinity tolerance. Cluster analysis could able to classify genotypes in three clusters based on observed traits. Principal component analysis could able to resolve four PCs explaining 85.87% of total variance in the data. Days to 50% heading, biomass and tolerance score were identified as key traits causing variation among genotypes. |
