基于灰色关联分析综合评估酥瓜品种的农艺性状

【目的】综合评估酥瓜新品种的主要农艺性状,筛选出适合三亚地区种植的酥瓜品种。【方法】在三亚地区进行酥瓜新品种田间比较试验,采用灰色关联分析法,综合评估供试9个酥瓜新品种的坐果率、商品率、产量、中心可溶性固形物含量、果肉厚度、种腔大小指数等6个主要农艺性状。【结果】各供试品种综合性状的等权关联度排序为N₆>绿牛>N₃>N₇>N₄>N₉>N₂>N₁>N₅,综合性状的加权关联度排序为绿牛>N₆>N₃>N₇>N₄>N₉>N₂>N₁>N₅。其中酥瓜新品种绿牛和N₆综合性状表现优良,排序靠前,N₁和N₅综合性状表现不理想,排序靠后。综合性状的加权关联度排序更符合田间观测结果。【结论】应用灰色关联分析法评估筛选出的酥瓜新品种绿牛和N₆综合性状表现优,适合在三亚地区推广种植。

Comprehensive Assessment for agronomic character of Crisp Melon (Cucumismelo.var. conmon Group) Cultivar Based on Grey Correlation Analysis

【Objective】 To assess the agronomic characters of new crisp melon cultivars comprehensively in the hope of providing new crisp melon cultivars suitable for planting in Sanya. 【Method】 The field experiment was conducted to compare agronomic characters of 9 new crisp melon cultivars in Sanya, Hainan. The main agronomic traits, including fruit setting rate, commodity rate, yield, soluble solid content in the center, flesh thickness and cavity size index, were assessed comprehensively based on grey correlation analysis. 【Result】 All the tested new crisp melon cultivars were ranked according to equal-weighted correlation degree between comprehensive characters, which were: N₆ > Lvniu >N₃>N₇ >N₄>N₉>N₂>N₁>N₅, and according to weighted correlation degree between comprehensive characters, they were as follows: Lvniu > N₆ > N₃> N₇ >N₄>N₉ > N₂> N₁ > N_5. Furthermore, Lvniu and N₆ ranked in the top 2 of all the cultivars, with good comprehensive characters, while N₁ and N₅ ranked in the last 2 of all cultivars, with poor comprehensive characters. The order of weighted correlation degree was more in line with the field observation results. 【Conclusion】 Lvniu and N₆ are screened out based on grey correlation analysis, which have excellent comprehensive characters, and are suitable for planting in Sanya.
