Leaf Anatomical Characters in Relation to Grain Yield of Wheat (triticum Aestivum L.) Cultivars

An experiment was carried out to study the variability of leaf anatomical characters of wheat (Triticum aestivum L.) cultivars and their association with grain yields. Results indicated that in most of the cases cultivar differences were significant. In respect of 6th leaf anatomical characters, simple correlation coefficients indicated that most of the leaf anatomical traits had significant negative relation with grain yield whereas in respect of flag leaf anatomical traits, only the association between radial dimension of big xylem vessel and grain yield was significantly negative and the correlation between number of veins and grain yield was significantly positive.
