Basing on our early stage research work about collection and description of sugarcane germplasm and the aided project of Yunnan Natural Science Fund (2001 C0015Q), the wild species Erianthus fulvus, which has good characters, cold-resistant, drought-resistant, higher Brix and less chromosome number, was utilized for the first time through intergeneric hybridization with sugarcane cultivar. Its F_1 hybrids were appraised with some new techniques and methods for germplasm enhancement.

本研究在课题组考察采集和保育鉴定甘蔗野生种质资源的前期工作基础上，依托云南省自然科学基金资助项目(2001C0015Q)，首次利用具有特异优良性状(抗旱、耐寒、锤度高、染色体数目少)的蔗茅野生种与甘蔗栽培种或品种进行属间远缘杂交，扩大甘蔗遗传多样性；采用新技术、新方法对蔗茅杂种F_1代材料进行早期鉴定评价研究，筛选具有育种价值的新种质，为进一步选育生态适应性广、抗逆性强、丰产高糖的甘蔗新品种奠定物质基础。

The results showed that karyotypic type of Ya01-21was 2n=104＝100m+4sm（4SAT）, Chromosome length ratio of the longest and the shortest 4.25, the average arm-ratio 1.35, belonging to 2C type of chromosome. Molecule identified combine with chromosome studied indicated that Ya01-21 was a progenies of Erianthus arundinaceum. following the law of n+n; ITS identify showed that Ya01-21 is a progenies of Erianthus arundinaceum, the somatic chromosome karyotypic type of Ya01-36 was 2n=132＝130m+2sm, Chromosome length ratio of the longest and the shortest 3.94, the average arm-ratio 1.27, belonging to 2B type of chromosome, combining the advance of characters the law of 2n+n can be resumed.

研究结果表明，崖城01－21的体细胞染色体核型公式为2n＝104＝100m+4sm（4SAT），最长与最短染色体的长度比为4.25，平均臂比1.35，染色体属2C型，分子鉴定结合细胞学研究认为其为斑茅的真实后代，其染色体遗传为n+n；崖城01－36经ITS签定为真实杂种，其体细胞染色体核型公式为2n＝132＝130m+2sm，最长与最短染色体的长度比为3.94，平均臂比1.27，染色体属2B型，结合其性状的进展，推断亲本向其传递染色体可能以2n+n的方式进行。
