Guttation fluid as a physiological marker for selection of nitrogen efficient rice (Oryza sativa L.) genotypes
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 کاملEffect of nitrogen supplying sources on nitrogen use efficiency in rice (Oryza sativa L. cv. Shiroudi)
The use of nitrogen fertilizer has a key role in enhancing agricultural productivity worldwide. In order to achieve an effective approach to enhance nitrogen use efficiency in rice, a field experiment was conducted in a randomized complete block design with three replications and 13 treatments on Shiroudi, a high yielding rice cultivar in Rice Research Institute of Iran (Amol) in 2015 and 2016....
متن کاملEvaluation and grouping of rice (Oryza sativa L.) genotypes of Central and West Asia using agronomic traits and grain yield
Rice is the staple food of half of the world's population and one of the most important crops in Central and West Asia. To assess variation in some important agronomic traits and grouping of rice genotypes, this study was performed and 49 genotypes from Azerbaijan, Kazakhstan, Afghanistan, Turkey, Kyrgyzstan, Iraq, and Uzbekistan along with 7 genotypes from Iran were evaluated using randomized ...
متن کاملPartial diallel analysis of agronomic characters in rice (Oryza sativa L.)
Rice (Oryza sativa L.) breeding seeking to combine high productivity and cold tolerance for the temperate Latin America region is an important challenge. We estimated some useful parameters which can be used to investigate the genetic control of agronomic characters in crosses combining cold tolerance and productivity. A partial diallel design was used in crosses between six tropical indica ric...
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...
