Research on Hybrid Breeding and Seed Germination Technology of Highbush Blueberry
摘要
Abstract
Objective] In order to innovate the germplasm resources and cultivate new varieties of blueberry.[ Method] Selecting 6 highbush blueberry cultivars, the effect of GA3 on the ermination rate of hybrid seed was studied using 4 pollination methods of artificial hybridization by setting 5 gibberellin solution soaking treatment.[ Result] Selecting open bud pollinate after emasculation, the seed setting rate of direct pollina-tion was the lowest, after 5 days emasculation rate was the highest.The 6 tested varieties had high cross compatibility.The seed setting rate, fruit setting rate was different and not positively correlated in different combinations .There was a big difference between the reciprocal cross of the same pair of parents in the seed setting rate.The seed setting rate, fruit setting rate of‘ Misty ×Sharpblue ’was the hightest,respectively 87.2%, 62.8%, the seed setting rate of‘legcy × O’ neal’ (65.4%) was the lowest, the fruit setting rate of‘Brigitta ×Southgold’ (41.5%) was the lowest.The mature period of hybrid fruit was ahead of time,and affected by the female parent.The germination time was sig-nificantly shortened at different concentrations of GA treatment, 200 mg/L GA3 was the best treatment of OS germination,more than 600 mg/L GA3 is not conducive to the germination of OX.The germination rate of hybrid seeds treated with different combinations of GA3 ranged from 35.0% to 75.0%, and the germination time ranged from 20 to 30 d.[Conclusion] The hybrid affinity of the same ploidy blueberry cultivars was higher.The pollination treatment of 3-5 days after emasculation was appropriate.Gibberellin treatment can significantly shorten the initial germination time of hybrid seeds.关键词
