摘要
为了摸清黔南山区玉米种质资源的类型、分布及其特点，１９９１～１９９４年对黔南山区进行了考察，共搜集玉米种质５９６份，主要有５个类型，其中硬粒型２２５份，占搜集数的３７．７５％；马齿型５０份，占８３９％；中间型５０份，占８．３９％；糯质型２０１份，占３３．７２％；爆裂型７０份，占１１．７５％。前３个类型（称普通玉米）品种繁多，分布最广，在黔南山区居主导地位，其分布特点是由西向东逐渐减少；后２个类型（称特用玉米）则以糯质型玉米分布较广泛，遍及黔南山区，而爆裂型玉米主要分布黔南、黔东南，以黔东南最普遍。通过初步鉴定、分析，对黔南山区玉米种质资源的特征特性、品质以及它们在当地农业生产中的作用有了一个基本的认识，并针对玉米生产现状，提出进一步发展玉米生产的建议。
The corn germplasm resources were explored in Qiannan mountainous ares during 1991-1994,in order to understand their peculiarity of the types and distribution. 596 varieties were collectedand divided into 5 major types:flint,dent,intermediate,glutinous and popcorn, the number ofvarieties was respectively 225,50,50,201 and 70,accounting for 37.75%,8.39%33.72%and 1.75%separately. The former 3 types(called general corn)had the most number of varieties and distributed widely,Their distribution showed the peculiarity of getting less fromthe west to the east,In the latter 2 types(called special corn),glutinous corn distributed inthe whole mountainous area,popcorn was mainly found in Qiannan and Qiandongnan areas,butthe most of them were cultivated in Qiandongnan.Through preliminary identification andanalysis on these resources we have basic understanding for their characters,quality and the role in the local agricultural production.A recommendation to further developing cornproduction was proposed based on the present situation.
