摘要
为筛选出适合河南地区种植的网纹甜瓜品种,对14个网纹甜瓜品种进行比较试验。结果表明:参试甜瓜品种中,品种zw20果实发育期最短,为39 d;品种zw6节间距最短,仅8.75 cm;品种风味四号叶绿素含量(SPAD)最高,为55.03;品种IVF303、翠蜜四号、IVF332产量分别为56 663.93、53 458.79、48 833.33 kg/hm2,显著高于其他品种,丰产性较好;品种zw20中心可溶性固形物含量达17.72%,明显高于其他品种;利用模糊数学中隶属函数分析法对参试品种品质、产量性状指标进行排名,品种zw20总隶属函数值为4.02,排名第1;zw20、zw11、甬甜7号、黄皮9818、IVF303、zy20等6个品种表现较好,可作为该地区网纹甜瓜品种引进的首要选择。模糊数学隶属函数法能够较客观地评价各品种表现,可辅助育种者、引种者对品种进行综合评价。
In order to select netted melon cultivars suitable for planting in Henan, 14 netted melon culti-vars were used to carry the comparison experiment. The study showed that the fruit development period of the cultivar zw20 was the shortest in the comparison cultivars, which was 39 days. The internodal length of zw6 was the shortest, which was only 8. 75 cm. The chlorophyll content of Flavor four was the highest, a-bout 55. 03（SPAD）. The yields per hectare of IYF303 , Cuimi No. 4 and IYF332 were 56 663. 93, 53 458.79 ,48 833. 33 kg respectively, which were significantly higher than other cultivars. The center soluble solids content of zw20 was 17.72% , obviously higher than other cultivars. Membership function a-nalysis method in fuzzy mathematics was used to rank the quality and yield traits index of the tested culti-vars. The total function value of zw20 was 4. 02,which was the first. The six cultivars zw20,zwl l ,Yong- tian 7 , Yellow peal 9818 ,IYF303 ,zy20 all showed good performance, which could be as the first choice to introduce. Membership function analysis method in fuzzy mathematics could objectively evaluate the perform-ance of the cultivars,which could assist breeders and introducers to evaluate the cultivars comprehensively.
