It performs well in yielding, lodging resistance, disease resistance, with a short duration of growth. Therefore, it is suitable to be grown in tropical areas and countries such as Myanmar and Indonesia. The male parent contains herbicide susceptible lethality gene and it is possible for mechanical mixed planting. The research analyzed performance of Hunyou No. 2 growth in Myanmar and the results showed that Hunyou No. 2 performed better in yield, panicle length, the number of seed per panicle, setting percentage, and thousand-seed weight than She thwe yin, as well as lodging resistance, disease resistance and quality. Some high-yielding cultivation measures have been concluded including sparsely sowing, densely planting, highlighting base fertilizers, and avoiding early water breaking.展开更多

A sample consists of 56 researchers who are working in Department of Agricultural Research, Department of Agriculture and Yezin Agricultural University, and involving varietal development of hybrid rice. The research instruments were a questionnaire used by 4 points Likert scale of strongly agree, agree, less agree and not agree to measure on researchers＇ attitudes towards 14 determinants of varietal development of hybrid rice production. The study revealed that the average age of the researchers was 46.5 years ranged from 25 to 60 years. The majority of researchers were 51-60 years old （41.1%）. The working experience of researchers ranged from 5 to 36 years and the metal of their experience was 20 years. The educational level was Ph.D. （35.7%）, M.Agr.Sc. （26.8%）, and B.Agr.Sc. （37.5%）. Majority of researchers were female （76.8%） and 58.9% were rice breeders. Moreover, 48.2% of researchers obtained the hybrid rice technology from breeding training and the researchers who believed in their current breeding works were 51.8%. Among 33 rice breeders, 72.7% of the rice breeders applied only convention breeding method. In addition, researchers＇ opinions on farmer＇s perception of hybrid rice technology, 60.7% of the researchers agreed on inferior grain quality and 73.2% of researchers strongly agreed on not stable market. This study found out more thin1 half of the researchers strongly agreed on 10 out of 14 determinmlts such as poor infrastructure, low human resource development, parental problem, insufficient experience, limit germplasm resource, limit research facilities, no incentive for breeders, weak public-private partnership, fewer quality breeders and not enough research fund. Moreover, half of the researchers agreed on 3 determinants likely need special technical training, need international assistance and climate change challenges. Finally, development of hybrid rice research in Mymlmar, there will be needed international assistmlce, and upgraded to hybrid rice research center from currently hybrid rice research section and need integrated hybrid rice policy supported by government.展开更多
