| Based on the crop grey breeding and expounded on the theory,and used in distribution of wheat varieties,wheat similar cultivation,and other areas,which fully shows that vitality and creativity of Grey crop breeding which from the theory of crop breeding and grey system theory on the verge of disciplines,breeder can be achieved by the practice of quantitative replace experience in crop breeding,and use science to weaken the arts,effectively reduced the errors which due to the inexperience and the subjective result it,so hase made breeding and cultivation decision-making to more accurate,reliable and scientific,Qualitative experience of traditional breeding and cultivation have a qualitative leap.In this paper,collation and analysis datas of Agricultural Sciences Institute in Anyang City(experimental unit) of 1998-2000 wheat varieties in Henan Province Regional Trial,the study drew out the Anmail varieties suitable area for the cultivation regional and similar grey cultivation techniques.The datas of An Mail,and other ten varieties,fourteen character,at thirteen experimental unit are used in this analysis of the experimental,to obtain the results of the pilot-weighted measure of vector-and the origin(center) distance.From the biological sense,the origin(center) is the ideal state of fourteen traits.In thirteen pilot projects to a representative of the types of ecological areas,the smaller the data the close to the ideal state of a variety of characters,the adaptation of the corresponding type of ecological zones.Anmailis most widely adaptability in all varieties.It most suitable the types of ecological zone as represented by Anyang,Shangqiu,Xuchang,West China,Suibing ecological type,the type suitable for the ecological zone is the representative of the ecological in Puyang,and Xinxiang,Kaifeng,Luohe,Pingyu type area.Experimental datas of sixteen traits of An Mail and other six large area planting varieties are used in this testig,adopting Gray resemblance cultivation principles and methods,gray similarity of Anmail and the other six species has obtain.An Mai 1 most similar with Yumai 21.Obviously,according to grey similar cultivation oprinciple,An Mai 1 should be adopted similar cultivation techniques with Yumai 21,then we will be able to achieve basically fine and good matching method and will get a better harvest.Yumai 21 has planted in the Northern Henan for years,is the dominant species in recent years,has been supporting cultivation measures,and more people have accumulated rich experience in the management field.Therefore,it is not difficult for Anmail to achieve fine-matching in variety and method.Datas from 2006 wheat production test in Henan Province are Used,in turn,studying the distribution of leading new wheat varieties at Henan Province.Zhengmai9694 is a new wheat varieties with a more extensive adaptation,foUowed by zhou mai20,and Yunong201,Zhengnong 17.Zhengmai 9694 is a new wheat varieties with a more extensive adaptation,high yield and agronomic traits are stability,Zhengmai 9694 and Zhoumai20 will be the dominant species in the future.In this paper,it has been affirmed that grey system theory applied in the distribution of wheat varieties,and also pointed the prominent problems of the subjects,in the use of grey distribution in wheat varieties and similar cultivated principle,choosing the characters which can represent the characters of the variety;distribution of Weight coefficientions must be in reason.put forward the next studing way and in dire need of solving problem in this subject,and pinted out the opinion of the investigater for this subject... |
