Production Of Black And Navy Beans In Virginia, Harbans L. Bhardwaj, Satya S. S. Narina Ph.D.

Virginia Journal of Science

An urgent need exists in Virginia and adjoining states to identify crops to replace declining tobacco acreage. Although not traditionally grown in the region, dry beans (Phaseolus vulgaris L.) have considerable potential as alternative summer crops due to their nutritional benefits and increasing consumer demand. Information on the production potential of these crops in Virginia, however, is not yet available. To remedy this situation, replicated field trials were conducted over three years with six black and four navy bean varieties to characterize grain yields following three row spacings and three planting times. Black beans significantly out-yielded navy beans (2095 …

Characterization Of Syntaxin 18 In Peregrinus Maidis And In Vitro Dsrna Synthesis For Potential Rnai-Mediated Control Of Maize Mosaic Alphanucleorhabdovirus (Mmv) Transmission, Hannah Corinne T. Cantaros, Charlene Niebres, Ruth Alessandra Banasihan, Argel L. Arenas, Karen B. Alviar

The Philippine Agricultural Scientist

The plant virus known as Maize mosaic alphanucleorhabdovirus (MMV) is a persistent, propagative pathogen transmitted by the corn planthopper Peregrinus maidis Ashmead (Hemiptera: Delphacidae). It is the causal agent for a mosaic disease that can cause significant loss in corn yield. Currently, disease management is focused on controlling its insect vector population. The molecular mechanisms of virus transmission by the insect vector are not yet fully understood. Previously, P. maidis syntaxin 18 (PmSTX18) was identified as a receptor for MMV. PmSTX18 interacts with the viral glycoprotein and potentially facilitates MMV recognition and entry into the vector, enabling virus …

Jurnal Kultivasi

The development of high-yielding hybrid maize is a strategic step to address global food demand amidst climate change. This study evaluates the agronomic performance of 14 maize genotypes—10 newly developed F1 hybrids and 4 commercial checks—under two planting densities (95,000 and 55,000 plants/ha) across three agroecosystems (lowland, midland, and highland). The objectives were to identify superior and adaptive genotypes and analyze genotype × environment interactions using AMMI and GGE biplot methods. Genotype G12 exhibited the highest yield (338.4 g/plant) at high density, especially in the highland, but showed poor stability. In contrast, G5 demonstrated consistent performance and stability across environments. …
