摘要 对Badila、BlackCheribon、Crystalina、粤糖57-423、Co419、闽糖70-611以及新引进的热带种57NG155、IJ76-315和Kropi等进行了人工开花诱导试验。除BlackCheribon和Crystalina外,其它参试品系均成功地诱导花开,这些品种在适当的处理条件下,开花率达30%以上,始花期提早至11月上旬至12月上旬,有效地解决了在海南甘蔗育种场自然 Experiments on artificial induction of flowering were carried out with Badila, Black Cheribon, Crystalina and some shy-flowering commercial varieties, as well as newly introduced S. officinarum clones, such as 57NG155, IJ76-315 and Korpi etc. AlI clones under experiment tasseled except Black Cheribon and Crystalina. The clones that produced flowers began flowering during early November and early December with tasseling rate of over 30% under the favorable treating conditions. From 1995/96 to 1998/99 crossing seasons, new S officinarum clones (including Badila) were used for crossing with clones of local S .spontaneum S. robustum S. barberi and Erianthus arundinaceus at Hainan Sugarcane Breeding Station. 50 crosses producing 66 pollened tassels were made. Some promising parental materials of broadened genetic basis have been selected from more than 8700 seedlings planted.
