灰色系统理论在爱玉子雄性品系性状综合评估中的应用

Application of Grey Correlation Degree Analysis in the Comprehensive Evaluation of the Male Strains of Ficus awkeotsang Makino

采用灰色系统理论,以抗病力、叶面积、花序数、花序长、花序宽、花序香气、落果数、苞口胶液、净蜂程度等9个主要经济性状为指标,对中国南方特有果树福建省栽培爱玉子的10个雄性品系的优劣进行综合评判和筛选,从而选出适宜在福建省推广栽培的优良品系。结果表明,雄性品系大洋74和浙江M2的综合评估值最为理想,综合品质最好,为优良品系,而大洋156和旗山M1综合评估值最差。因此,可将雄性品系大洋74和浙江M2与优良的雌性品系共同配植,从而提高爱玉子产量。研究结果对于爱玉子品系选育及推广栽培具有重要的参考价值。

According to the grey correlation degree analysis,9 economic characters of 10 male Ficus awkeotsang strains in Fujian province were judged comprehensively and selected.Some excellent strains were selected for large scale use in Fujian.The result showed that the comprehensive characters of male Ficus awkeotsang strain Dayang 74 and Zhejiang M2 were the best,and those of Dayang 156 and Qishan M1 were the worst.The male strains Dayang 74 and Zhejiang M2 could be cultivated with good female strains to promote yield.The results have important reference value for Ficus awkeotsang cultivation and breeding.
