Ergot, caused by Claviceps purpurea (Fr.:Fr.) Tul., is an important disease of grasses grown for seed. Ergot can be especially severe in Kentucky bluegrass (Poa pratensis L.) seed production, with yield losses estimated as high as 25% (2). Claviceps purpurea invades the ovary, replacing the potential seed with a hard black sclerotium. Sclerotia are typically one to several times longer than the...

Given the urgency of rising sea levels and need to sustain food production, developing flood-tolerant crops is essential. The aim this study was assess genetic potential cross CO51x13-6 (NIL CO43Sub1) in BC2F4 BC2F5 generations using Parent Offspring regression analysis. Significant variation observed across a wide range traits both generations. distribution important traits, including plant he...

This experiment was conducted to study the variability parameters of forty rice genotypes evaluate genetic i.e., Genotypic coefficient (GVC), Phenotypic (PVC), Heritability (H) and mean percent Genetic advance (MGA) for nine different yield yield-contributing traits at Agriculture Research Farm, Banaras Hindu University, Varanasi during Kharif-2018. The data were collected attributing subjected...

Genetic improvement has been devoted to increasing rice yield by the spikelet number per panicle and spikelet/leaf ratio. As a result, indica-japonica hybrid “Yongyou” varieties with large panicles superhigh potential have developed. These exhibit significantly higher grain nitrogen use efficiency for (NUEg) under moderate high N supply conditions due their sink size, but performance remains ob...

Rice yield can be increased in many ways such as developing new high yielding varieties or adopting proper agronomic management to the existing varieties. Proper fertilization is an important management practice to increase rice yield. Proper fertilization can markedly increase the yield and improve the quality of rice [1]. Nitrogenous fertilizer has immense effect on rice yield throughout the ...

background and objectives: evaluation of the grain yield and yield components and also morphological traits can help to identify strategies for selection of resistant cultivars and increased crop yield production under heat stress condition. to this end, in experiment to evaluate of grain yield and yield components on 42 rice lines tolerant to heat stress from international rice research instit...

Inflorescence architecture is a key agronomical factor determining grain yield, and thus has been a major target of cereal crop domestication. Transition from a spread panicle typical of ancestral wild rice (Oryza rufipogon Griff.) to the compact panicle of present cultivars (O. sativa L.) was a crucial event in rice domestication. Here we show that the spread panicle architecture of wild rice ...

The stigma exertion rate is a polygenic inherited trait that is important for increased seed yield in hybrid rice breeding. To identify quantitative trait loci (QTL) associated with high stigma exertion rate, we conducted QTL mapping using 134 recombinant inbred lines derived from XieqingzaoB and Zhonghui9308, which have high and low stigma exertion rates, respectively. A total of eight QTLs (q...
