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。Abstract: 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 maintaining 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.
