Abstract To determine the impact of sorghum variety and salicylic acid concentration on growth characteristics yield crop, a field experiment was applied in spring 2022 at second agricultural research station College Agriculture Al-Muthanna University Al Bandar area (about 3 km from city center). The used split plots arranged completely random sector randomized design. Items were plotted main p...

ٍearly watergrass (echinochloa oryzicola (ard) fisher) is an aggressive specie of echinochloa and have mimicry chareterstics of rice . in order to evaluate competitive effect of aggressive specie of echinochloa on rice, an experiment was conducted at the rice research institute of rasht during 2007. the experimental design was complete randomized block with three replications. the treatment incl...

Panicle size has a high correlation with grain yield in rice. There is a bottleneck to identify the additional quantitative trait loci (QTL) for panicle size due to the conventional traits used for QTL mapping. To identify more genetic loci for panicle size, a panicle developmental trait (LNTB, the length from panicle neck-knot to the first primary branch in the rachis) related to panicle size ...

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...

<p>Rice is an essential staple food in Nepal but researches and varietal improvement programs are rarely carried out due to inadequate variability study. The field study was diagnose the influence of genetic environmental factors on yield traits aid future rice breeding programs. Twelve genotypes were arranged randomized complete block design with three replications from July November 201...
