Rice yield is a complex trait that strongly affected by environment and genotype × interaction (GEI) effects. Consideration of GEI in diverse environments facilitates the accurate identification optimal genotypes with high performance, which are adaptable to specific or environments. In this study, multiple trials were conducted evaluate grain (GY) four yield-component traits: panicle length, n...

Cytokinins (CTKs) regulate panicle size and mediate heat tolerance in crops. To investigate the effect of high temperature on panicle CTK expression and the role of such expression in panicle differentiation in rice, four rice varieties (Nagina22, N22; Huanghuazhan, HHZ; Liangyoupeijiu, LYPJ; and Shanyou63, SY63) were grown under normal conditions and subjected to three high temperature treatme...

The present study consists of 21 rice genotypes including one check variety that were evaluated in 2021 to genetic variability, correlation and path coefficient for thirteen quantitative characters. Observation recorded the variability parameters, yield its attributing traits. On basis mean performance MTU-1224 was found be superior grain per hill followed by, BPT-329, KNM-118 MTU-1001 give hig...

Panicle caterpillars comprise an economically important insect pest complex of sorghum throughout the Great Plains of the United States, particularly in Kansas, Oklahoma, and Texas. The sorghum panicle caterpillar complex consists of larvae of two polyphagous lepidopteran species: the corn earworm, Helicoverpa zea (Boddie), and fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noc...

in the current study, a set of 96 recombinant inbred lines (ril) at f8, derived from a cross between two varieties, anbarbu (sensitive to drought stress) and sepidroud (tolerant to drought stress) were used. the experiment was performed at gonbad kavous located in the golestan province of iran in 2010–2011 using two augmented designs at normal and stress conditions, separately. the ril populati...

genetic variations within the species of agropyron desertorum and 2 varieties of a. cristatum subsp. pectinatum var. imbricatum and a. cristatum subsp. pectinatum var. pectinatum were studied using morphological traits and total protein profiles (with sodium dodecylsulphate polyacrylamide gel electrophoresis). an experiment was conducted in research institute of forests and rangelands (2012-201...

Climate change increases the drought-affected areas, which challenge breeders to develop adaptive and drought-tolerant rice cultivars. The study aimed determine heritability, gene action controlling of various traits in upland F4 populations derived from cross, Sileso (high yielding drought tolerant) × Ciherang (early maturing), obtain high-yielding early-maturing lines. populations, along with...

Rice (Oryza sativa L.) inflorescence (panicle) architecture is an important agronomic trait for rice breeding. A number of high-yielding japonica rice strains, characterized by an erect panicle (EP) of their architecture, have been released as commercial varieties in China. But no EP-type indica varieties are released so far. Here, we identified two allelic erect-panicle mutants in indica rice,...
