    Characterization of diverse wheat germplasm for Zinc and Iron content under different environments
    (CCSHAU, Hisar, 2020) Rana, Vineeta; Munjal, Renu
    The present investigation was conducted to study Zinc and Iron content in grain and straw of wheat. The research was done in two experiments having different environment. For the first experiment 278 wheat germplasm lines were grown under fertilization and without fertilization condition and their effect on physiological, yield and quality parameter were studied. Analysis of data revealed that Zinc and Iron content in grain was almost same in both fertilization and without fertilization condition but Zinc and Iron content in straw was maximum in without fertilization condition. Biomass, grain yield and 100- grain weight was found to be high in fertilization condition. Out of these 278 lines, 16 were selected for the second experiment on the basis of high Zinc content, high Iron content and high grain yield. The 16 selected germplasm lines along with four checks were tested under timely sown and late sown condition. The effect on physiological and biochemical parameters was studied at anthesis, 10 days after anthesis and 20 days after anthesis. NDVI and chlorophyll stability index was found more in timely sown at anthesis. Activity of SOD was maximum in timely sown at anthesis. Activity of LOX and ADH was maximum in timely sown at 20 days after anthesis. Biomass, grain yield, no. of productive tillers, no. of grains/spike, grain weight/spike, 1000-grain weight was found high in timely sown condition. Zinc and Iron content was high in timely sown condition in both grain and straw. SG249, SG152 and SG47 showed highest Zinc and Iron in grain. SG249, SG95 and SG47 showed highest Zinc and Iron in straw.
