Phenotyping of elite zinc rich rice varieties for agronomic traits and grain zinc content
An experiment was carried out to explore high zinc(Zn) donors to be amenable for use as parents in zinc biofortification programme. A semi-dwarf rice breeding line IR 128773-4-4-2-2-B revealed high tillering ability, slender kernel feature (KL ≥ 8.0 and KL/KB˃ 4.0), acceptable grain filling (fertili...

| description | An experiment was carried out to explore high zinc(Zn) donors to be amenable for use as parents in zinc biofortification programme. A semi-dwarf rice breeding line IR 128773-4-4-2-2-B revealed high tillering ability, slender kernel feature (KL ≥ 8.0 and KL/KB˃ 4.0), acceptable grain filling (fertility%) with maturity duration 120-125 days. It had shown significantly higher yield than Swarna (Check), while BRRI Dhan 72 and DRR Dhan 45 were at par to this check variety. IR 128773-4-4-2-2-B and few local land races (Malliphulajhuli, Nikipankhia and Tikimahsuri) exceeded 40 ppm grain zinc content. Among these, IR 128773-4-4-2-2-B seem to have merit for use as zinc dense donor parent owing to its excellent agronomic features coupled with high grain zinc content. |
