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...
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...
STOCK DEFINITION AND GEOGRAPHIC RANGE The gray whale formerly occurred in the North Atlantic Ocean (Fraser 1970), but is currently only found in the North Pacific (Rice et al. 1984). The following information was cons idered in classifying stock structure of gray whales based on the Dizon et al. (1992) phylogeographic approach: 1) Distributional data: two isolated geographic distributions in th...

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...
Over the past 50 years, thousands of rice varieties have been introduced by plant breeders to agricultural communities all over the world. Despite the improvement of attributes such as grain yield and tolerance to biotic and abiotic stresses, a significant portion of farmers still prefer local varieties over the improved cultivars. The main reasons for this perference are the absence of a dire...
