Abstract
Durum wheat (Triticum durum L.) serves as the main raw material for high quality pasta products and
diverse range of foods. Its high protein content, gluten strength, kernel hardness, size, golden amber color, high
beta-carotene content and excellent cooking quality makes it most suitable for preparation of wide range of
products. Therefore the present investigation was carried out to identify durum wheat genotypes superior in
grain quality traits. Thus 36 durum wheat genotypes (NIVT-4) grown during the winter season of 2012-13
in the field of Wheat and Barley Section, Department of Genetics and Plant Breeding were evaluated for
various biochemical, physico-chemical, morphological parameters besides micronutrients and grain yield
attributes. Leaf samples collected at the heading stage were used for the estimation of morphological parameters.
The genotypes viz. HD 4730, PDW 337, WHD 954 and PBND 1625 were found promising for flag leaf area,
specific leaf weight and plant height. The genotypes UAS 448, PDW 337 and HD 4728 were out performed with
respect to biochemical parameters. Quality parameters viz. protein content, crude fibre and gluten were found
higher in three genotypes viz. PDW 337, UAS 448 and WHD 954 while β-carotene content was highest in RKD
255 (6.87 μg/g). Other genotypes viz. NIDW 793 and WHD 953 also had more than 6.5 μg/g β-carotene content.
Sedimentation value of 44 ml was found in PDW 337 and DDW 27. Lysine content was found maximum in WHD
954. The genotypes PDW 337 and UAS 448 had better physical characteristics with respect to grain appearance
score, grain hardness and hectolitre weight. The genotypes PDW 337 and UAS 448 recorded higher values of Fe
and Mn content while genotypes MACS 3931 and PDW 335 recorded higher concentrations of Zn and Cu
respectively. The genotypes HD 4730, WHD 954 and PBND1625 showed better performance for most of the yield
related traits. Significant and positive correlation among different quality and yield traits were also observed.
