基于模糊隶属函数法的波罗蜜品种比较试验

以2个优良品系及6个审定品种为材料,对果实的农艺性状及品质性状进行比较,并基于以指标变异系数赋权的模糊隶属函数法,对波罗蜜果实品质、产量进行综合评价,筛选和评价波罗蜜优良品系。结果表明不同品系果实可溶性糖、可滴定酸、抗坏血酸、可溶性固形物含量,糖酸比,平均单株产量等指标差异极显著；8个品系综合评价排名为：33号＞324号＞2号＞327号＞45号＞408号＞28号＞20号。以果实大小评判,则大果类型324号产量较高,中果类型33号产量较高,2号品质、风味最优,45号次之,小果类型28号品质较优。

Comparison Test of Jackfruit Strains Based on Fuzzy Membership Function Method1

Using 2 excellent strains and 6 certified varieties as materials, the agronomic and quality characters of the fruit were compared, and based on the fuzzy membership function method weighted by the index variation coefficient, the fruit quality and yield of jackfruit were comprehensively evaluated, screened and evaluated. Evaluate excellent strains of jackfruit.The results showed that the fruit soluble sugar, titratable acid, ascorbic acid, soluble solid content, sugar-acid ratio, average yield per plant and other indicators of different strains were significantly different;the comprehensive evaluation ranking of 8 strains was: 33>324>2>327>45 >408>28>20.If judged by fruit type, the yield of 324 among the large fruits is higher, the yield of 33 among the medium fruits is higher, 2 is the best in quality and flavor, the second is 45, and the quality of 28 among the small fruits is better.
