A survey was carried out in two states, six locations of south east Nigeria during the normal flowering period for three (3) consecutive years to evaluate intraspecific variations phenology African pear flowering. The different types species growing forest, distant and nearby farms, including homesteads were used. 60 trees 180 flowered branches sampled survey. Parameters collected include time ...

Sorghum is one of the most important crops worldwide. An accurate and efficient high-throughput phenotyping method for individual sorghum panicles needed assessing genetic diversity, variety selection, yield estimation. High-resolution imagery acquired using an unmanned aerial vehicle (UAV) provides a high-density 3D point cloud with color information. In this study, we developed detecting char...

Abiotic stress seriously affects the yield of rice (Oryza sativa L.). Grain yield in rice is multiplicatively determined by the number of panicles, number of grains per panicle, and grain weight. Here, we describe the molecular and functional characterization of STRESS_tolerance and GRAIN_LENGTH (OsSGL), a rice gene strongly up-regulated by a wide spectrum of abiotic stresses. OsSGL encodes a p...

Grasses produce tiller and panicle branching at vegetative and reproductive stages; the branching patterns largely define the diversity of grasses and constitute a major determinant for grain yield of many cereals. Here we show that a spatiotemporally coordinated gene network consisting of the MicroRNA 156 (miR156/)miR529/SQUAMOSA PROMOTER BINDING PROTEIN LIKE (SPL) and miR172/APETALA2 (AP2) pa...

Rice blast, caused by the fungal pathogen Magnaporthe oryzae, is a major constraint to rice production worldwide. In this study, we developed monogenic near-isogenic lines (NILs) NIL Pi9, NIL Pizt , and NIL Pi54 carrying genes Pi9, Pizt, and Pi54, respectively, by marker assisted backcross breeding using 07GY31 as the japonica genetic background with good agronomic traits. Polygene pyramid line...

Plant breeders have focused on improving plant architecture as an effective means to increase crop yield. Here, we identify the main-effect quantitative trait loci (QTLs) for plant shape-related traits in rice (Oryza sativa) and find candidate genes by applying whole genome re-sequencing of two parental cultivars using next-generation sequencing. To identify QTLs influencing plant shape, we ana...

Grain yield is a quantitative trait, which determined by several agronomic traits. Unfortunately, there little information about the genetics behind components in US rice cultivars. The objectives of present study were to (1) conduct QTL identify chromosome (chr. hereafter) regions associated with traits two U.S.-developed cultivars and (2) candidate genes major related Four evaluated summer 20...

The present study consist of 29 rice genotypes including one check variety that were evaluated at Field Experimentation Centre the Department Genetics and Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology Sciences, Prayagraj U.P. to genetic variability, heritability, advance, correlation path coefficient for 13 quantitative characters. experiment ...
