Rice (Oryza sativa) is one of the most important food crops in the world. Numerous quantitative trait loci or genes controlling panicle architecture have been identified to increase grain yield. Yet grain yield, defined as the product of the number of well-ripened grains and their weight, is a complex trait that is determined by multiple factors such as source, sink and translocation capacity. ...

to compare the yield and yield components of 10 promising dryland barley genotypes with a conventional cultivar (reihan03), a field experiment was conducted based on a randomized complete block design in miyaneh region in the 2010-2011 growing season, and their agronomic and morphological traits were recorded. genotypes were significantly different in terms of all the studied traits, and genoty...

to study the nature and magnitude of gene effects, heritability and number of effective factors for grain yield and some yield components in rice, six generations viz., p1, p2, f1, f2, bc1 and bc2 were prepared from the crosses of shapasand × irfaon-215 and irfaon-215 × saleh and grown in a randomized complete design with three replications. results of analysis of variance showed significant di...

Sixty four parental lines of hybrid rice were evaluated for genetic divergence by taking into account nine traits during two seasons year 2018. By resolving the ten groups, Ward's clustering method demonstrated having significant diversity. Cluster X had most (13) out all clusters, followed cluster II (12 genotypes). The line clusters IX, VIII, VII, V, and IV, which correspond to SD-5, SD-2, HS...

In order to investigate the effects of drought stress on grain yield and its components, a study was carried out (2011) as split plots in randomized complete blocks design in Isfahan (32° 40'  N,51° 48' E). Main factor was drought stress in four levels including irrigation after 80, 100, 120, and 140 mm evaporation from evaporation pan (class A) and subplots were three cultivars (Sirena, Record...

The field experiment for the current study was carried out at rice research station in Najaf governorate, affiliated with Iraqi Ministry of Agriculture. To know response three cultivars to spraying natural honey solution different. factorial using a randomized complete block design replications. results showed significant effect various factors their interactions on characteristics present stud...

in order to study the effect of different levels of the manure and foliar application of zn and mn fertilizers on the quantitative and qualitative yield of soybeans (var. williams), a factorial experiment was conducted in a randomized complete block design with three replications in 2012. treatments involved three levels of fertilizer: manure (zero as control; six and 12 t/ha), two levels of mn...

in order to study morphological traits, yield and yield components of 34 hybrids of corn, an experiment was carried out based on of randomized complete block design with three replications under normal irrigation condition in khorasan razavi agricultural research and natural resources center, mashhad, iran on 2009. results of analysis of variance showed that there were significant differences b...
