Abstract
The status of crossing utilization of sugarcane germplasm in Sugarcane Research Institute, Yunnan Agricultural Academy from 1998 to 2002 was reviewed. After several year's research, the plant age and photoperiod for flowering inducement of various parents were determined, which increased flowering rate of Saccharum officinarum, quickened the flowering of F1 which originally flowered late, promoted the flowering of F1 and BC1 which were hard to flower, and increased the rate of fertile pollen. Meanwhile, with the improving of crossing technique, crossing efficiency was increased, and some elite materials were selected out from the crossing combinations of S.officinarum, local varieties and famous parents.
