摘要
簸箕柳(Salix suchowensis Cheng)与杞柳(Salix integra Thunb)的正反交杂种具有明显的杂种优势。通过无性系选择,选育出高产优质的编织柳优良无性系——簸杞柳Jw8-26(Salix suchowensis×S.integra)和杞簸柳J_w9-6(S.integra×S.suchowensis),其柳条平均产量分别为1941公斤/亩和1746公斤/亩,平均条长分别为230厘米和234厘米,产量和条长比对照簸箕柳高82.91—63.64％和16.75—14.25％,是适于江淮平原和长江中下游地区推广的编织柳优良无性系。
This paper presents the results of the notable hybrid vigour made by the sexual reciprocal hybridization with Salix suchowensis and Salix integra and two wicker clones with good quality and high output made by clonal sele-ction-Jw8-26(Salix suchowensis S.integra Jw8-26)and Jw9-6(Salix integra S. suchowensis Jw9-6).
The clone Jw8-26's average yearly yield of coppice shoot is 1941 kg. per mu, and the clone Jw9-6's 1746 kg,per mu.The clone Jw8-26's average length of coppice shoot is 230 cm and the clone Jw9-6's 234 cm. This is an increase of 82.91-63.64% as compared with the yield of coppice shoot of the parents; and an increase of 16.75-14.25% as compared with the length of coppice shoot of the parents. These fine varieties of two wicker willow's clones Jw8-26 and Jw 9-6 could be used to plant in the middle and lower Yangtze valley and in the plain between the Yangtze river and Huaihe river.
