栝楼新品系区域试验

采用区域试验的方法,对比大田优选的栝楼新品系KXY-001与传统栝楼品系在植物学性状、物候期特征及产量等方面的差异。结果表明,KXY-001植株主干明显,生长迅速,丰产稳定性强;KXY-001定植后当年即可开花结果,第二年即进入丰产期,二年生和三年生植株亩产鲜果较传统品系分别增产78.48%及41.25%;KXY-001总皂苷质量分数连续三年均高于传统对照品系,分别高4.54 %、7.27 %、5.08 %。KXY-001新品系具有较高的产量及稳定的区域适应性,综合性状优于传统品系,适宜在山东栝楼道地产区栽培种植和推广,该研究结果对于进一步挖掘特定栝楼种质特点、品系推广及资源的高值化利用具有一定借鉴意义。

Regional test performance of new Trichosanthes kirilowii strains

The differences in botanical characters, phenological characteristics, and yield between the new Trichosanthes kirilowii line KXY-001 and the traditional Trichosanthes kirilowii line were compared by regional test. The results showed that KXY-001 had obvious trunk, rapid growth, high yield, and stability. Further, KXY-001 could blossom and bear fruits in the first year after planting and enter the high yield period in the second year. The fresh fruit yield per mu of biennial and triennial plants increased by 78.48% and 41.25%, respectively, compared to the traditional strains. The total saponin content of KXY-001 was higher than that of the traditional control strains for three consecutive years, which were 4.54%, 7.27%, and 5.08% respectively. KXY-001 new line has higher yield and stable regional adaptability, and its comprehensive characters are better than the traditional lines. It is suitable for cultivation and promotion in Shandong Trichosanthes kirilowii real estate area. The research results have certain reference significance for further unveiling specific germplasm characteristics of Trichosanthes kirilowii, line promotion, and high value utilization of resources.
