This study was conducted to analyze the correlation among grain yield, yield components, duration of vegetative and grain filling periods in twelve oat (Avena sativa L.) cultivars at the Research Farm of the College of Agriculture, Isfahan University of Technology, from 2001 to 2003. A randomized complete block design with three replications was used. The correlation coefficients among the grai...
We characterized a rice introgression line, YTH34, harboring a chromosome segment from a New Plant Type (NPT) cultivar, IR65600-87-2-2-3, in the genetic background of an Indica Group elite rice cultivar, IR 64, under upland and irrigated lowland conditions in Japan. The number of panicles (as an indicator of tiller number) and number of spikelets per panicle of YTH34 were lower than those of IR...
Nitrogen (N), auxin and cytokinins (CTKs) play important roles in regulating the growth of rice tiller buds. However, little is known about the underlying mechanisms and the relationships between them in the regulation of tiller bud growth in rice. In the present study, N and auxin indole-3-acetic acid (IAA) were used to regulate tiller bud growth in Nanjing 44 rice, a japonica cultivar. The ti...
Rice is a worldwide important grain crop, which is considered as the main food and most important source of providing protein and calories for people in the world. Correlation analysis of different traits and yield components with the grain yield is a very important issue in the selection and breeding programs of genotypes. The experiment was performed in the form of completely randomized ...
ABSTRACT Most sandy soils have low natural fertility and levels of organic matter, making nitrogen (N) fertilization essential. Thus, five doses N were applied (0, 75, 125, 175 225mg dm-³) in a randomized block design to evaluate the effects on morphogenetic, structural production characteristics Brachiaria brizantha cv. Marandu Quartzarenic neosoil. The did not affect height canopy. leaf elong...
Maximum tiller number and productive tiller number are important traits for wheat grain yield, but research involving the temporal expression of tiller number at different quantitative trait loci (QTL) levels is limited. In the present study, a population set of 371 recombined inbred lines derived from a cross between Chuan-Nong18 and T1208 was used to construct a high-density genetic map using...
to evaluate of rice genotypes in various modified systems, an experiment was carried out as split plot in randomized complete blocks design with four replications at neka region, mazandaran province, iran in 2011-2012. cropping systems were chosen as main plots including conventional, improved and system of rice intensification (sri) and genotypes as sub plots including: sang tarom, hashemi tar...
For QTL mapping of related salt tolerance QTLs and determining the contribution of each QTL to phenotypic variation, a population consisting of 96 F2:3 families derived from the cross Kharchia (parent tolerant) and Gaspard (susceptible parent) were evaluated during 2 years. Of the 92 microsatellite markers used to evaluate parents, 32 markers were polymorphic which were used for analysis. Three...
