The genetic analysis and improvement of characters, such as tuber processing quality traits and yield components which tend to be quantitatively inherited, are far more difficult than those at diploid potato. Reviewing the earlier studies indicated that a few systematic investigations on genetics of important traits in potato were untaken and most focused on estimates of combing ability for agronomic traits due to limited materials and methodologies available.

objective in order to investigate the variety of the airborne fungi in jingzhou area and study the relationships between airborne fungi and allergic diseases.methods we surveyed the fungi sensitizing of air in jingzhou city from feb.1th,2007 to jau.31th,2008 to quantitatively observe the daily airborne fungi and count under microscope through one year.results the fungi spores were present through all year.more than 20 taxa of airborne fungi have been collected,among which the most common fungi were uredinales,ustilaginales,alternaria,etc.fungi spores were ralated with the season and weather,the most aboudant period in sring and summer.conclusion the airborne fungi were seen one year and were mostly allergenic.many of then had seasonal distribution.

目的：调查荆州市气传真菌的种类、数量变化及飘散规律，了解优势菌群与过敏性疾病的关系，为荆州市空气真菌过敏症的防治提供参考。方法：2007年2月1日至2008年1月31日，在荆州市设曝片点，每日换片，收集全年气传真菌样品，在显微镜下统计，定量获得每天及全年的真菌数量。结果：全年均可见真菌孢子，共收集真菌种类20多种，其中最常见的有链格孢、锈菌、黑粉菌等，其数量和季节、气候有关，以春季、夏季最多，秋季和冬季依次降低。结论：气传真菌全年均有分布并具有较强的致敏性，部分真菌具有明显的季节性变化。
