In this study 90 individuals of recombinant inbred lines (RILs) were developed by crossing subspecies of japonica rice cultivar, ‘Nagdong’ and an indica type cultivar, ‘Cheongcheong’. These individuals were used to identify the quantitative trait loci of panicle traits using SSR markers. A genetic linkage map was constructed using one hundred fifty four simple sequence repeat ...

Although the rice growth response to FACE (free-air CO2 enrichment) has been widely studied and is considered important within the scientific community, few studies have attempted to examine the effects of FACE on the yield of indica rice, which is typically the parent of indica hybrids in China. The effects of FACE on the yield, yield components, biomass, N uptake and leaf photosynthesis of Ya...

This study aims to determine the genetic variance and heritability of yield component agronomic character some new plant type (NTP) rice genotypes planted on two different locations. The research was arranged in randomized complete block design (RCBD) with 12 treatments three replications as a blok nested location (in locations, i.e.: East Lampung Tanggamus. treatment consisted 10 genotypes, IP...

to determine rice yield loss resulting from blast disease (magnaporthe grisea) at the corp's different growth stages, a field experiment was conducted at the rice research institute of iran, rasht. rice local cultivar hashemi was transplanted to 3×4m plots for the experimental treatments (time of disease evaluation) each treatment was replicated 4 times. under natural infection conditions,...

Number of spikelets per panicle (NSP) is a key trait to increase yield potential in rice (O. sativa). The architecture of the rice inflorescence which is mainly determined by the length and number of primary (PBL and PBN) and secondary (SBL and SBN) branches can influence NSP. Although several genes controlling panicle architecture and NSP in rice have been identified, there is little evidence ...

a randomized complete block design with three replications was performed in rice research institute of iran, rasht in 2008, to find the effect of supplement foliar application of nitrogen and potassium on ’daylam‘ hybrid rice grain yield, its components and grain protein percentage. foliar application of 20 kg nitrogen (5 percent n) and 15 kg potassium (3 percent k2o) in different pre-anthesis ...

An experiment was conducted at Instructional Farm, Department of Agronomy, Faculty Agriculture, AKS University, Sherganj, Satna (M.P.) during Kharif season 2019-2020. The consisted randomize block design having Factorial arrangement in three replications. In this experiment, 12 treatment combinations including four different age seedlings D1-12 days, D2-18 D3-24 days and D4-30 old seedlings, wh...

Aim This study investigated the impacts of system rice intensification (SRI) and conventional management practice (CP) on growth, grain yield, nitrogen use efficiency by application. Methods Field experiments were conducted in wet dry seasons; each season, experiment was set a split-plot randomized complete block design triplicate with crop practices main plots levels subplots. Results The aver...
