摘要
1993年和1995年先后两次在湖南道县玉蟾岩遗址发现一万年以前的古栽培稻谷,这是迄今为止所发现的最早的古栽培稻。初步观察分析,粒长与普通野稻相近,粒宽介于粳稻和籼稻之间,长宽比、稃毛长度、稃肩角度等特征介于普通野稻和籼稻之间,稃面双峰乳突属“钝型”与粳稻相似,外稃顶端无芒。是一种兼有野、籼、粳综合特征的演化早期的原始栽培稻。故建议定名为“玉蟾岩古栽培稻”。
The 4 ancient rice before 12000~14000 BP of Yuchanyan of Hunan Daoxian
in 1993 and 1995 were discovered. The grain longth of the ancient rice is like O. rufipogon, the
width is between keng and hsien, the ratio of L/W. longth of glume hair and angel of glume
shoulder are between O. rufipogon and hsien. The bi-peaked-tubercle is like keng but no awn.
It is a original cultivated rice that has characters of O. rufipogon, hsien and keng. It be named
'Yuchanyan ancient cultivated rice' were proposed.
