Phenotyping Rice (Oryza sativa. L) Genotypes for Nitrogen use Efficiency
نویسندگان
چکیده
Aim: Global food security has become a serious issue, nitrogen fertilizer use increased agricultural productivity globally, but at significant environmental cost. The present study was aimed to identification of rice genotypes from the existing germplasm or development cultivars that can make best N in low soils is essential for sustainability agriculture
 Study Design: experiment laid out split plot design with three levels as main plots and twenty five subplots.
 Place Study: screening conducted December 2021April 2022 wetland, Tamil Nadu Agricultural University, Coimbatore.
 Methodology: Twenty were cultivated 0% Recommended Dose Nitrogen (RDN) (T0), 50% RDN (T1), 100% (T2) control under field conditions, morphological traits such plant height, leaf area; number tillers, total dry weight recorded along photosynthetic efficiency (PNUE).Two-way ANOVA Cluster analysis used analyze data.
 Result: results revealed among genotypes, G3 highest (25.10) followed by G7 (22.62) (T0). lowest PNUE G11 (5.99) (T2). Across exhibited NUE.
 Conclusion: Observations relies upon genotype exhibit high shows efficiency.

A field experiment was conducted during the rainy season of 2008 and 2009 to use guttation fluid as a physiological marker for the screening of more nitrogen efficient rice genotypes on the basis of relationship between Guttation Fluid (GF) oozed by leaf tip and nitrogen use efficiency (NUE), grain yield (GY) and biological yield (BY) amongst five rice (KRH-2hybrid, Kasturiaromatic, Krishna Ham...
متن کاملMapping quantitative trait loci for nitrogen uptake and utilization efficiency in rice (Oryza sativa L.) at different nitrogen fertilizer levels.
Genetic improvement is the fundamental basis for improving nitrogen-use efficiency. A better understanding of genetic factors controlling nitrogen uptake and utilization is required for crop genetic improvement. In this study, we identified the quantitative trait loci (QTLs) associated with traits of nitrogen uptake and utilization by using the single-sequence repeat marker method and a recombi...
