The capacity to discriminate variations in day length allows plants to align flowering with the most favourable season of the year. This capacity has been altered by artificial selection when cultivated varieties became adapted to environments different from those of initial domestication. Rice flowering is promoted by short days when HEADING DATE 1 (Hd1) and EARLY HEADING DATE 1 (Ehd1) induce ...
The world's population is increasing very rapidly, reducing the cultivable land of rice, decreasing table water, emerging new diseases and pests, and the climate changes are major issues that must be addressed to researchers to develop sustainable crop varieties with resistance to biotic and abiotic stresses. However, recent scientific discoveries and advances particularly in genetics, genomics...
The study was conducted at Dr. Emilio B. Espinosa, Sr. Memorial State College of Agriculture and Technology (DEBESMSCAT) Cabitan, Mandaon, Masbate. experimental design used 3 x 7 CRD factorial with three varieties mushrooms (Pink Oyster, White Abalone, Milky Mushroom), seven agricultural substrates as treatments, Treatment A (70% rice straw 30% sawdust), B corn cob), C Carbonized Rice Hull), D ...
Rice husk and straw are by-products of rice cultivation and processing industry and can be used as an energy source. Proper understanding of the physical properties of rice residues is necessary for utilizing them in thermochemical conversion processes such as gasification and combustion. The physical properties (moisture content, particle size, bulk density and porosity) of rice husks and stra...
Salt stress reduces the yield and quality of rice. It is great significance to screen out salt-tolerant varieties for development utilization saline land. The study was carried on 114 rice varieties; first, seven were selected treated with different salt concentrations (0, 50, 85, 120, 155, 190, 225 mM), traits, including germination energy, capacity, shoot length, root number, plant fresh weig...
Grain size affects the yield and quality of rice. The large grain line (LGL), showing a japonica-like genome, was selected in breeding field. 94 F2 plants derived from cross between LGL Hanareum (a high-yielding tongil-type variety) were used for quantitative trait loci (QTL) analysis length (GL), width (GW), thickness (GT). A linkage map population, covering 1312 cM all 12 chromosomes, constru...
A total of 18 rainfed upland New Rice for Africa (NERICA) varieties were categorized as the heavy panicle and low tillering types and early heading, in compared with 32 different varieties. These chromosome components were clarified using 243 SSR markers which showed polymorphism among NERICA varieties and their parents, CG 14 (O. glaberrima Steud.) and one of the recurrent parents, WAB-56-104 ...
With the ever-increasing global demand for high quality rice in both local production regions and with Western consumers, we have a strong desire to understand better the importance of the different traits that make up the quality of the rice grain and obtain a full picture of rice quality demographics. Rice is by no means a 'one size fits all' crop. Regional preferences are not only striking, ...
Rice is the staple food for more than half of the world’s population. Although rice production has doubled in the last 30 years as a result of the development of high-yield, widely adaptable, resource-responsive, semi-dwarf varieties, the threat of a food crisis remains as severe as it was 60 years ago due to the ever-increasing population, water scarcity, labor scarcity, shifting climatic cond...
abstract in order to optimum utilization of diazinon on rice stem borer, chilo suppressalis walker (lepidoptera: pyralidae), an experiment was conducted with two factors including, rice varieties (tarom-mahalli, khazar, nemat) and application times (control with no application, first generation application, second generation application, first and second generations application and four times a...
