摘　　要：以柚子为父本，选择福桔优良单株为母本进行杂交，培育珠心苗进行福桔的品种提纯复壮。运用高接换种的方法可使珠心苗提早2～3a开花结果，缩短童期，并保持了福橘优良性状，显著地提高了品质。对珠心苗高接植株多年观察及品质鉴定，认为珠心胚植株在品质上表现较大差异。选出优良福桔珠心系“新农1号”、“新农2号”和“新农3号”3个株系，其中新农1号株系可溶性固形物达14．2％，单果种子数仅8粒，单果重118g，具有丰产、果大、色艳、种子少、可溶性固形物高等优良性状。To purify and rejuvenate the variety of C. reticulata Blanco ＂Fuju＂, pomelo was used as the pollen parent and Fuju the maternal plant to cultivate nucellus seedlings. Applying the top-grafting-exchanging-variety technique, the flowering and fruiting age of the nucellus seedlings was advanced by 2-3 years. The juvenile period of Fuju was cut short and the fruit quality improved while maintaiuing its original desirable characteristics. After years of observation and assessment on the top-grafting plants of nucellus seedlings, considerable quality variations were found among nucellus embryo plants. Three strains of superior varieties were identified： ＂Xinnong 1＂, ＂Xinnong 2＂ and ＂Xinnong 3＂. They had high fruit yield, large fruit size, bright peel color, less seeds and high content of soluble solids. For example, Xinnong 1 strain contained 14. 2% soluble solids, averaged 8 seeds, and weighed 118 g per fruit. This variety is recommended for expanded cultivation.
