花药培养技术是一条快速高效的育种途径,它与杂交育种相结合,既可发挥杂交育种的优点,又能提高选择效率,加速稳定,缩短育种年限。我所自70年代初就开始研究水稻花药培养,20年来,无论在基础理论还是在育种实践上都取得了很大进展,育成了多个品种(系)。并在生产上占有一定的种植面积。现将最新推广的水稻优良花培新品种龙粳3号的特性及栽培要点简介如下。龙粳3号水稻品种,原代号龙花83—046,是我所于1980~1982年以[(合江21号×雄基9号)×合江16号]×滨旭的组合方式杂交,1983年接种 F_1花药离体培养选育而成。1992年经黑龙江省农作物品种审定委员会审定,确定推广。
Anther culture technology is a fast and efficient breeding method. Combining with hybrid breeding, anther culture technology can not only play the advantages of hybrid breeding, but also improve the selection efficiency, accelerate the stability and shorten the breeding period. Since the early 1970s, I started to study rice anther culture. In the past 20 years, I have made great progress both in basic theory and in breeding practice, and have cultivated many varieties (lines). And in production occupy a certain area planted. Now the latest promotion of new varieties of fine hybrid rice cultivar Longjing 3 characteristics and cultivation points are as follows. Longjing 3 rice varieties, the original code Longhua 83-046, is my from 1980 to 1982 with [(Hejiang 21 Xiongji 9) × Hejiang 16] × Bin Xu combination of hybridization, 1983 Inoculation F_1 anther culture in vitro. In 1992 by the Heilongjiang Province Crop Variety Approval Committee validation, to determine the promotion.
