| 1 | Detecting mislabeling and identifying unique progeny in Acacia mapping population using SNP markers显示文摘Acacia hybrids offer a great potential for paper industry in Southeast Asia due to their fast growth and ability to grow on abandoned or marginal lands. Breeding Acacia hybrids with desirable traits can be achieved through marker assisted selection(MAS) breeding. To develop a MAS program requires development of linkage maps and QTL analysis. Two mapping populations were developed through interspecific hybridization for linkage mapping and QTL analysis. All seeds per pod were cultured initially to improve hybrid yield as quality and density of linkage mapping is affected by the size of the mapping population. Progenies from two mapping populations were field planted for phenotypic and genotypic evaluation at three locations in Malaysia,(1) Forest Research Institute Malaysia field station at Segamat, Johor,(2) Borneo Tree Seeds and Seedlings Supplies Sdn, Bhd.(BTS) field trial site at Bintulu, Sarawak, and(3) Asiaprima RCF field trial site at Lancang, Pahang. During field planting, mislabeling was reported at Segamat, Johor, and a similar problem was suspected for Bintulu, Sarawak. Early screening with two isozymes effectively selected hybrid progenies, and these hybrids were subsequently further confirmed by using species-specific SNPs. During field planting, clonal mislabeling was reported and later confirmed by using a small set of STMS markers. A large set of SNPs were also used to screen all ramets in both populations. A total of 65.36% mislabeled ramets were encountered in the wood density population and 60.34% in the fibre length mapping population. No interpopulation pollen contamination was detected because all ramets found their match within the same population in question.However, mislabeling was detected among ramets of the same population. Mislabeled individuals were identified and grouped as they originated from 93 pods for wood density and 53 pods for fibre length mapping populations.On average 2 meiotically unique seeds per pod(179 seeds/93 pods) for wood density and 3 meiotically unique seeds per pod(174 seeds/53 pods) for fibre length mapping population were found. A single step statistical method was used to evaluate the most informative set of SNPs that could subsequently be used for routine checks for mislabeling in multi-location field trials and for labelling superior clones to protect breeder's rights. A preliminary set of SNPs with a high degree of informativeness was selected for the mislabeling analysis in conjunction with an assignment test. Two subsets were successfully identified,i.e., 51 SNPs for wood density and 64 SNPs for fibre length mapping populations to identify all mislabeled ramets which had been previously identified. Mislabeling seems to be a common problem due to the complexity involved in the production of mapping populations. Therefore, checking for mislabeling is imperative for breeding activities and for analyses such as linkage mapping in which a correlation between genotypic and phenotypic data is determined. | Asif Javed Muhammad Mohd Zaki Abdullah Norwati Muhammad Wickneswari Ratnam | 2017 | Journal of Forestry Research2017，28，6： | 1 |

| 4 | Simple Approach on Intermixing Solar and Wind Energy and Minimizing Their Intermittent Effect显示文摘Renewable energy resources especially wind and solar energy are emerging as the modern power sources to electrify remote areas. The main reason behind their emergence is due to their environment-friendly behavior,unlimited availability and short period for replenishment over nonrenewable energy resources. Renewable energy resources are much better than nonrenewable energy resources, but the intermittency in renewable energy resources degrades the system performance. In order to overcome the intermittency, multiple hybrid system techniques were proposed in literature that can achieve suitable results but have disadvantages of complicated control structures and high implementation cost. Considering aforementioned shortcomings, a simple balancing approach is proposed to intermix solar and wind energy together so as to utilize the available energy from both sources at a given time.It is very common that solar farms are the dominating source of energy in daytime and summer, while wind farms are the dominating source of energy at night and in winter. The proposed approach delivers maximum possible power to the load by combining dominating and non-dominating resources all the time, hence mitigating the intermittency of individual resources. Compared with other approaches, the proposed approach offers key benefits with redundancy, simple design and low cost, which can be analyzed from simulation results. | KARNI Awais 罗利文 MUMTAZ Muhammad Adnan ZAKI Atta ul Munim | 2019 | Journal of Shanghai Jiaotong university(Science)2019，24，1： | 1 |
| 5 | Investigation of availability,demand,targets,and development of renewable energy in 2017-2050:a case study in Indonesia显示文摘Abundant potential of renewable energy(RE)in Indonesia is predicted to replace conventional energy which continues to experience depletion year by year.However,until now,the use of RE has only reached 2%of the existing potential of 441.7 GW.The main overview of this work is to investigate the availability of RE that can be utilized for electricity generation in Indonesia.National energy demand and targets in the long run during the 2017-2050 period are also discussed.Besides,government policies in supporting RE development are considered in this work.The results show that the potential of RE in Indonesia can be utilized and might replace conventional energy for decades.The use of RE for electricity generation can be achieved by employing a government policy that supports the investor as the executor of RE development.The selling price of electricity generated from RE is cheaper than electricity generated from fossils;this makes economy is more affordable for people.Finally,the target set by the government for utilizing RE as the main energy in Indonesia can be done by implementing several policies for the RE development.Thus,greenhouse gas emissions and the use of petroleum fuels can be reduced. | Erdiwansyah Erdiwansyah Mahidin Mahidin Husni Husin Nasaruddin Nasaruddin Khairil Khairil Muhammad Zaki Jalaluddin Jalaluddin | 2021 | International Journal of Coal Science & Technology2021，8，4： | 0 |
