| 1 | Investigation and Analysis of Harmful Organisms Intercepted from Imported Seeds and Seedlings during 2011-2014显示文摘In this study,records published by General Administration of Quality Supervision,Inspection and Quarantine of China and related literature on harmful organisms intercepted from imported seeds and seedlings during 2011-2014 were investigated and analyzed.The results showed that the species and amount of harmful organisms intercepted from imported seeds and seedlings increased gradually during 2011-2014,which posed a realistic or potential threat to agriculture production in China.Based on the present situation,corresponding suggestions and countermeasures were proposed:1 strengthening the study on rapid detection technology of harmful organisms;2 improving the ability of animal and plant quarantine in China. | Anyu GU Xiaolin LI Yuran XU Jian HU Jinwen ZHANG Wei DENG Yonggang LU Wei NIAN Yangjun DONG Chundao YANG Jianping DUAN Zhongmin YANG | 2015 | Agricultural Biotechnology2015，4，2： | 0 |
| 2 | Analysis on the Breeding and Major Traits of Wide-adaptability Indica CMS Line Yungu 3A显示文摘Breeding sterile lines is the key to the development of hybrid rice with wide adaptability. However,at present,few wide-adaptability sterile lines have been applied in production practice. In this study,Yungu 3A,a new WA-type Indica CMS line with good grain quality,was developed by hybridization between Yunfeng 66 A with wide adaptability as female parent and F1 plants of Yunfeng 66 B / D62 B as male parent and continuous backcrossing. According to the results,the finally obtained Indica CMS line Yungu 3A has good plant type and leaf shape,strong tillering ability,excellent flowering habit,stable and complete male sterility with the sterile plant rate and pollen sterility rate of 100%,strong combining ability,high outcrossing rate,low sensitivity to light and temperature,and strong disease resistance,which was approved by Yunnan Provincial Crop Variety Appraisal Committee in 2013. Yungu 3A is conducive to the development of new hybrid rice combinations with good quality and wide adaptability,exhibiting a promising prospect of application. | Yonggang LU Huafeng DENG Jinwen ZHANG Wei DENG Yuran XU Anyu GU Wei NIAN Zhiliang LU Xiaolin LI | 2015 | Agricultural Biotechnology2015，4，3： | 0 |
