[目的]为芒果杂交育种工作提供理论依据。[方法]研究广州甘蔗糖业研究所海南甘蔗育种场59个常用芒果亲本与32个亲本摘花处理后连续3年的始花期。[结果]结果表明,亲本的始花期具有遗传力较高的性状,广义遗传力达0.9514164。亲本的始花期年际间差异在4～26d,平均为9.6d。年际间变化在0～10d内(含10d)的占66.2%,在10～20d内(含20d)的占33.9%。32个亲本摘花处理后的始花期年际间最大差异在1～20d,同一品系在同年份较亲本的始花期可推迟15～21d。[结论]采用摘花技术可使早花品系与迟花品系的花期相遇,达到杂交的目的。 [Objective] The research aimed to provide theoretical basis for mango hybrid breeding. [Method] The initial florescence of 59 mango parents and 32 parents of Hainan sugarcane breeding farm in Hainan Cane Sugar Industry Institute for 3 consecutive years were studied. [Result] The results showed that the initial flowering stage of the parents had high heritability, and the heritability of generalized heritability reached 0.9514164. The difference of the initial flowering period between parents was 4 ~ 26 days with an average of 9.6 days. The interannual changes were 66.2% in 0 ~ 10 days (including 10 days) and 33.9% in 10 ~ 20 days (including 20 days). The maximum difference in flowering period between the 32 parents after flowering was between 1 and 20 days, and the same flowering period of the same strain could be delayed 15 to 21 days. [Conclusion] Using the technology of picking flowers, the flowering of early flowering and late flowering could be met to achieve the purpose of hybridization.
