Evaluation of stability and yield potential of upland rice genotypes in North and Northeast Thailand

Journal of Integrative Agriculture 2018年第1期17卷 28-36页

The planting of upland rice is one cropping option in area with limited water availability and low soil fertility in North and Northeast Thailand. The varietal selection was determined by grain yield potential, wide adaptation, and good stability. This study was aimed at evaluation of indigenous upland rice germplasm for yield and yield stability in multi-locations. Thirty-six upland rice genotypes collected from six provinces of the North and Northeast Thailand and one check variety （sewmaejan） were assessed under five locations in the rainy seasons of 2009 and 2010. The experiment was laid out in a randomized complete block design with three replications. The genotype grain yield was highly affected by location （59.90%）, followed by genotypes （G）xlocation （L） interaction （12.80%） and genotype （6.79%）. The most suitable location for the genotype eval- uation was L3 （Khon Kaen-KKU 10） which associated with stability of grain yield for all genotypes. Furthermore, biplot and regression analysis indicated that genotype numbers 6 （Jaowmong 1）, 10 （Neawmong 1）, 18 （Neawdum 1）, 19 （Leamna）, 20 （Prayaleamkang）, 32 （Kunwang 2）, and 33 （Kunwang 3） showed great yield stability over five locations. The genotypes will be applicant for upland rice production area and parental base in breeding program.

Investigating the influence of gamma ray energies and steel fiber on attenuation properties of reactive powder concrete

The effect of gamma ray energies and volume ratio of micro steel fiber(1 and 1.5%) on attenuation properties of reactive powder concrete(70 MPa compressive strength) was investigated. Different characteristics have been considered such as linear attenuation coefficient,mass attenuation coefficient, and half-value *** iodide crys.al with a gamma ray spectrometer and collimated beam of gamma ray has been implemented to perform the experimental test. Three sources(Cs-137, Co-60, and Bi-207) with energies of(0.662, 1.17 1.33, 0.569,and 1.063) MeV were adopted in the test. The results obtained indicated that mass attenuation coefficient is proportioned inversely with gamma ray energies and directly with a volume ratio of micro steel fiber. The linear attenuation coefficient and half-value thickness of the tested samples have been calculated and discussed. The obtained results showed that increasing the volume ratio of steel fiber has modified the adequacy of the reactive powder concrete as a shielding element since it increases the density and reduces the half-value thickness.

Introduction One of the key objectives of gastroenterology(GI)fellowships is to teach fellows how to perform high-quality endoscopic procedures[1].The primary model for this education is the apprenticeship approach,in which fellows perform endoscopic procedures on patients under the supervision of an attending gastroenterologist[2].Critical to the success of this teaching model,faculty should deliver timely and actionable feedback based on direct observation of the fellow’s endoscopic performance[3].
