１９９１－１９９５年，对本所保育的１９７份甘蔗野生资源，重点是割手密（Ｓ．ｓｐｏｎｔａｎｅｕｍ）的开花习性，形态特征，生物学特性，抗逆性等与杂交育种利用直接有关的性状作了观测，研究和分级，结果表明：四川甘蔗野生资源类型丰富，主要野生资源割手密的花期较长，分蘖力强、高抗黑穗病、抗旱、抗寒、高锤度（＞＝１６％）材料所占比例较高，其中有两份材料的锤度多次在成熟高峰期达２２％，这一表现居目前国内外已报导的同类材料之首。这些具有较高利用潜力和利用可能性的珍贵野生资源可在今后的品种和亲本创新计划中应用。 In 1991-1995, 197 wild sugarcane resources conserved in our institute were focused on the flowering habits, morphological characteristics, biological characteristics and resistance of S.spontaneum, which were directly related to the cross breeding The results showed that the sugarcane resources in Sichuan Province were rich in wild type, longer flowering time, stronger tillering ability, smut resistance, drought resistance, cold resistance and high brix (> = 16% ) Material accounted for a higher proportion, of which two materials brix repeatedly in the peak of 22% during the mature period, the performance of the current domestic and foreign reports have been the first of its kind. These precious wild resources with high utilization potential and utilization possibilities can be applied in future variety and parental innovation programs.
