| 摘 要： | １９８７年以来，发现仅现雌蕾的全雌性苎麻，经自然结实及其与黑皮蔸杂交，创造出８个全雌性苎麻可株系，经感光性鉴定为光周期敏感型全雌性苎麻材料，ＳＧ０型与黑皮蔸具有一定程度的杂交亲合笥；ＳＧ型的体细胞染色体倍性变异异常，具有多样性。

| Abstract: | Since 1987, gynoecious ramie with only fcmale bud appearance have been discovered. Eight gynoecious ramie plant system havebeen produced through its natural bear fruit and it as mother plant were hybridized with Heipidou as father plant. Gynoecious ramieare Photoperiodical Sensitive Gynoecious Ramie (to be called "SG Ramie" for short)by appraisal of photosenstization. Between "SG0 Ramie" and Heipidou has some affinity of hybridization. SG type for organic cells chromosome multiple showed variation of abnormal and varied. Parts of SGtype have a shorter plant - lower fibre ratio of fresh bast, but have better fibre quatily. It is consid-ered that SG type is useful for ramie breeding and is very advantageous to study photoperiod-reaction and heredity of sexual types. |
