Abstract

Zinc utilization efficiency (ZUE) and effect of total leaf zinc (Zn) on productivity were examined in 22 germplasm lines of rice. The results revealed that there was a significant genetic variability within high and low leaf Zn types with regards to ZUE and the genotypes with low leaf Zn showed relatively high ZUE. A positive significant relationship was seen between total leaf Zn and grain yield and also with total dry matter (TDM). Increasing Zn acquisition may have a positive effect on growth, development and productivity in rice genotypes.
