Research ArticleOpen accessEvery word in the titleDrought Tolerance and Evaluation of Genetic Changes in Rice Mutant LinesAryanti Amsal, Ishak-ishakThe genetic improvement of rice through mutation induction to obtain drought resistance is essential for stable and adequate rice production would enable us to anticipate the rice yield-reducing effects of global warming. The aim of this research was to evaluate the rice mutant lines showing tolerance to drought condition and their genetic relationship using SSR markers. Mutant lines were obtained … …American Journal of Applied Sciences, Vol. 15, Issue 1 · 16 Jan 2018 · 8,547 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhysiological and Molecular-Genetic Evaluation of Rice Breeding Resources on Cold Tolerance for Creating New Varieties for the Northern Zone of Rice CultivationYeldos Almabekovich Zhanbyrbayev, Aiman Bokenovna Rysbekova, Bakdaulet Naubaevich Usenbekov et al.This study was aimed at assessing cold tolerance of rice breeding materials produced in Kazakhstan and foreign countries in the phase of seed germination, creating initial cold-tolerant forms and lines to derive Kazakhstan varieties of rice and identifying in the selection material the genes of the quantitative loci of cold tolerance (qPSST-3, qPSST-7 and qPSST-9), based on the molecular-genetic approach. … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 23 Sep 2017 · 7,416 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSome Features of Rice Cultivation Agrotechnics in Kazakhstani Aral Sea RegionZhazira Baiserikovna Zhumatayeva, Asset Myrzakhanuly Toktamyssov, Kurmanbek Bakiruly et al.The article presents the results of a study of high quality agrotechnics that allowed to use Marzhan, Yantar and AySaule rice varieties under the stress conditions of Kazakhstani Aral Sea region. In particular, the different seeding rate of seeds of rice (6.5, 7.0 and 7.5 million of germinating seeds per hectare) and application rates of the main types of mineral … …OnLine Journal of Biological Sciences, Vol. 17, Issue 2 · 10 Jun 2017 · 7,656 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Time of Flooding Occurrence is Critical for Yield Production in Rice and Vary in a Genotype-Dependent MannerJenjira Mongon, Arom Jantasorn, Prateep Oupkaew et al.Flash floods occur in rainfed lowland and flood-prone areas and have a profound incidence on crop yield, which is tightly linked to worldwide food insecurity. The most flooding-threatened crop is rice. Under this condition, rice undergoes anoxic and post-anoxic shock that affects its growth, development capacity and ultimately causes an important grain yield loss. Therefore, the introduction of submergence-tolerant varieties … …OnLine Journal of Biological Sciences, Vol. 17, Issue 2 · 3 Jun 2017 · 8,093 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleConstrained Modified Genetic Algorithm for Optimizing RICE Climate Change Model PolicyHaitham OsmanThe objective of this paper is to use evolutionary algorithm for policy making to help in decision support, the Regional Integrated Climate-Economy (RICE) model for the dynamic climate change is used to optimize the tradeoff policy between abating of carbon dioxide emissions to reduce global climate change and in the other hand the resulting in economic damages. A Constrained Genetic … …American Journal of Applied Sciences, Vol. 14, Issue 10 · 12 Apr 2017 · 7,508 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIdentifying Factors Influencing Production and Rice Farming Income with Approach of Path AnalysisMax Nur Alam, EffendyThis research analyzes direct and indirect factors that potentially affected rice quality, rice price at the farmers' level, rice production and farming income. The target population in this research were farmers who farmed on rice land area ranging from 0.5 to 2.0 ha. A multistage, stratified cluster sampling was used in this research. This research employed a survey of 300 … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 1 · 21 Mar 2017 · 9,003 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Social Impacts of Rice Distribution Program for Poor PeopleThamrin TahirThis research aims at identifying the social impacts of rice distribution program at Batua in Panakukkang district, Makassar city. This research is a kind of survey research. In this research, the technique of data analysis is a qualitative descriptive that explores research results descriptively. The research results showed that there is no impact economically, because the distribution is only enough … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 21 Feb 2017 · 7,357 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleValidation of SSR markers associated with Submergence Tolerance in Rice (Oryza sativa L.)Kirill V. Azarin, Alexander V. Usatov, Andrey V. Alabushev et al.The present work is devoted to the validation of SSR markers associated with submergence tolerance (Sub1A) QTLs in rice. It was shown that only microsatellite markers RM 7481 differentiates donor lines and recipient variety. Based upon the results of DNA analysis with the marker of the RM 7481 of the F2-plants, the 14 homozygotes by the locus Sub1A, 40 samples … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 19 Dec 2016 · 7,634 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFactors that Influence Rice Production and Technical Efficiency in the Context of an Integrated Crop Management Field School ProgramMoh. Nur Rasyid, Budi Setiawan, Moch. Muslich Mustadjab, Nuhfil HananiThis research estimates the effect of production input on rice production and the effect of socio-economic factors on the technical efficiency of rice farms in the program of the Integrated Crop Management Field School (ICMFS). Data were collected from 78 rice farmer household heads from two randomly chosen villages in Indonesia. The results show that seed, fertilizer, pesticide and labor … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 14 Nov 2016 · 8,182 accessesView PDFCite
