The results indicated that the seed yield per plant showed a significant positive correlation with most of traits like days to 50% flowering, height, filled grains panicle, number spikelet fertility, flag leaf width, numbers tillers plant, effective panicle length and 100 weight, representing importance these for development great yielding varieties in contrast trait sterility has been reported...

Fifty two genotypes were evaluated to find out the genetic variability, character association, and path coefficient for reproductive traits of exotic rice germplasm in experimental field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur during December 2008 to May 2009. The analysis of variance showed significant variation for all the characters indicating wide geneti...

The present study was undertaken with the objective to determine the nature and magnitude of variability, degree of association between yield and it`s component characters and their direct, indirect effects on grain yield in rice (Oryza sativa L.). Thirty three genotypes were evaluated for identifying their efficiency with respect to 20 yield and quality traits. High heritability with high gene...

Stomatal distribution is found to be an important trait of rice cultivars for increasing yield. A total of six rice cultivars, three from each of inbred and hybrid cultivars, were used to study stomatal distribution on the leaf epidermis and its influence on yield and yield attributing characters of rice during the Boro season. The hybrid cultivars exhibited superiority in respect of number of ...

Th is research was carried out to identify quantitative trait loci (QTLs) controlling yield and yield components in rice using 196 F2:4 lines derived from a cross between two rice varieties of indica, Sepidrood and Gharib. Quantitative trait loci analysis using composite interval mapping was carried out by 105 SSR and 111 AFLP markers. Results showed that 8 chromosomes contain 28 regions (QTLs)...

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...
