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...
Water deficit caused a serious threat to crops, especially panicle development at reproductive growth phase. We investigated grain yield components and gene expression profiles of panicle among tolerant and sensitive rice in response to drought stress. Panicle morphologies exhibited that secondary branches per panicle were more severely affected as compared to primary branches per panicle. More...
Simplifying the selection procedure to improve yield of new genotypes of rice is necessary. in order to evaluate relationship among grain yield and other agronomic traits, an experiment was conducted in agricultural and natural resoures research center in 2015-2016 year. In present study, 10 rice genotypes were studied in randomized complete blocks design with three replications. Grain yield al...
Panicle length (PL) is an important trait for improving panicle architecture and grain yield in rice (Oryza sativa L.). Three populations were used to identify QTLs and candidate genes associated with PL. Four QTLs for PL were detected on chromosomes 4, 6, and 9 through linkage mapping in the recombinant inbred line population derived from a cross between the cultivars Xiushui79 (short panicle)...
In order to investigate the effect of nitrogen fertilizer and plant density on the agronomic characteristics of rice cv. Tarom Hashemi, a field experiment was carried out as a randomized complete blocks design with three replications during 2018 and 2019 in a farm located in Sari, north of Iran. The present study consisted of 10 levels of plant density (hills m-2) and N fertilizer, named T1 (20...
FRIZZLE PANICLE (FZP) and RFL/ABERRANT PANICLE ORGANIZATION 2 (APO2) play important roles in regulating the ABCDE floral organ identity genes. However, the relationships among FZP and these floral identity genes in the regulation of panicle formation remain unclear. Here, we used the novel mutant fzp-11, wild-type and FZP-overexpressing plants to compare the expression of these genes during pan...
Panicle size and architecture are traits of major relevance for oat production as they play a key role in conditioning the potential number grains per spikelet consequence grain shape, size, distribution. The aim this research was to propose an image-based strategy methodology evaluate panicles. Specifically, goals were create deploy foundations high-throughput phenotype panicles determine opti...
quantitative valuations of observed heterosis for 11 traits of 15 f1 hybrids generated by half diallel crosses of six diverse rice cultivars (domsefid, hashemi and binam, three iranian local cultivars; dorfak, kadous and ir30, three improved cultivars), were made in this study. fifteen f1 hybrids and their parents were evaluated in a randomized complete block design with three replications at t...
according to coates’s (2004, as cited in zhang, 2010) definition of "conversational dominance" (p.111), it refers to the phenomenon of a speaker dominating others in interaction. specifically, it means how a speaker makes use of certain strategies to get the floor and maintain the floor. thus, the amount of talk is the main measurement for the dominance of the conversation. whether a speaker do...
The genetic basis underlying the relationship between the source leaves (the top two leaves) and the sink capacity in rice was investigated in a replicated trial of 2418 F2 derived F4 progeny from an inter-subspecific cross between cv. Lemont (japonica) and cv. Teqing (indica) and a complete linkage map with 115 well distributed RFLP markers. Path analysis indicated that 50% of the phenotypic v...
