Abstract:

Phosphorus (P) deficiency is a major constraint to rice production worldwide. Especially developing countries like India, having a limited access to P fertilizer. Genetic variations in rice in terms of root length, density of root hairs, modified root architecture, have been observed in low P concentration. Adaptive root modifications enhance P acquisition but are often associated with yield penalty. Rice genotypes with desired root traits along with better P utilization efficiency are required. The present study was conducted to evaluate the effect of phosphorus deficiency stress on root traits of diverse rice genotypes. Roots of rice genotypes grown in root rhizotron having soil P (P2O5 ≤ 7.59kg/ha), with and without P supplementation were compared for difference in total root length, lateral branching, surface area and volume. Significant difference was observed among the genotypes, due to inherent genetic makeup and also in their response to P deficiency stress. While an average decrease in all four root traits was recorded, few genotypes showed P deficiency induce lateral root development manifested as total root length, root surface area and volume. The three genotypes (Buddha, R-RF-78 and Cross 116) were identified as P deficiency tolerant rice genotypes, for use in further P efficient development of rice varieties.
