摘　　要：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, characters including flowering speciality, form, biologecal speciality and resistance to adverse growing conditions, were estimated for 197 clones of wild sugarcane germplasm, especially, S. spontaneum in our institute. The clones were graded upon the expresson of characters. The results showed: the forms of wild germplasm were various and wide spreaded in Sichuan Province. There were clones with longer flowering time, higher tillering rate and high resistence to smut, dry and cold. Many S. spontaneum clones are high in brix (> = 16% ). Brix of 22% was achieved by two chones.
