石刁柏(Asparagus officinalis L.)是雌雄异株异交植物。目前栽培面积达60万亩左右。生产上用种主要依靠进口,种籽常有混杂、退化、性状分离等现象。因此,实现良种种籽自给,已成为我国石刁柏生产中亟待解决的问题。我所于1989～1990年开展了石刁柏品种有性杂交技术研究工作,两年来共做194个组合,授粉2932朵花,结实1475粒果,结实率为50.3％,发芽率为82.3％。现将初步研究结果 Asparagus officinalis L. is a dioecious plant. The current cultivation area of ​​about 600000 acres. Production mainly rely on imports of species used, the seeds often mixed, degradation, trait separation and so on. Therefore, to achieve good seed self-sufficiency has become a problem to be solved urgently in the production of asparagus. In 1989 ~ 1990, we carried out research on sexual hybridization of asparagus varieties. In the past two years, 194 combinations were made, pollinating 2,932 flowers and sturdy 1475 fruits, with a seed setting rate of 50.3% and a germination rate of 82.3%. Now preliminary study results
