摘  要：
稻米的香味性状是衡量稻米品质好坏的最重要指标之一,对市场售价有着重要的影响。作为亚洲栽培稻起源及遗传变异中心的云南,具有丰富的香稻种质资源,香稻资源的利用潜力巨大。本研究对192份云南稻种资源进行了系统的鉴别,并根据参照品系的香型进行分类,同时探讨水稻叶片与精米的香型的相关关系。结果表明31.21％的云南稻种有不同程度的香味。叶片和精米的香味表型有差异。供试品种叶片、精米均有香味的材料占11.46％。叶片不香而精米香的材料占10.19％。叶片香而精米不香的材料占9.55％。叶片和精米香味的相关系数为0.03。

摘  要：
Aroma is one of most important characteristics of rice, and it greatly affects marketing value of developed rice varieties. As one origin of Asian rice cultivars, Yunnan is rich in aroma rice germlasm, which is potentially to be used as parental parents in variable breeding programs. The objectives of this study were to systematically evaluate the aroma characteristics of 192 accessions of random sample of Yunnan rice germplasm. Based on a set of reference breeding lines, which possessed distinct aroma types, all accessions were characterized. A correlation between plant leaf and corresponding well milled rice was analyzed on degree of aroma performance. The results suggested that 31.21% of Yunnan rice germplasm possess certain degree of aroma. There were differences on aroma performance between plant leaf and corresponding well milled rice. Among the aroma accessions, there were 11.46% aroma both in plant leaf and well milled rice, 10.19% nonaroma in leaf while aroma in milled rice, 9.55% aroma in leaf while nonaroma in milled rice. The correlation coefficient between plant leaf and milled rice were observed as 0.03. It is insignificance.
