摘要
为筛选沙棘优良杂交种质资源,本试验以杂交F_1代及其父母本与对照品种中雌沙棘共13份材料为试材,通过调查比较物候期、生长性状、生长速率及果实性状等相关指标,通过建立隶属函数方程,对10份杂交F_1代材料进行综合评价。结果表明,杂交F_1代果实成熟期为8月13日—15日,介于中国沙棘与蒙古沙棘之间。参试材料平均株高为284.68 cm,平均冠幅为205.85 cm,平均地径为5.47 cm,中蒙杂交沙棘生长性状指标显著高于对照品种中国沙棘雌株与楚伊沙棘,具有树势强,生长速率快的特点。果实百果重平均值为30.33 g,俄罗斯大果沙棘品种楚伊百果重显著高于其他参试材料,中国沙棘雌株百果重最低,为11.21 g。单株产量平均值为8.28 kg,高于母本楚伊沙棘与对照品种中国沙棘雌株,其中中蒙杂雌6材料单株产量最高,为12.25 kg,中国沙棘雌株材料单株产量最低,为2.43 kg。通过综合评价,中蒙杂雌6与中蒙杂雌10综合评价E值高于其他材料,可以作为中熟杂交沙棘种质资源进行保存与推广种植。
In order to screen excellent hybrid germplasm resources of seabuckthorn,this experiment used a total of thirteen female seabuckthorn materials from the hybrid F 1 generation,its parents,and the control variety as the test materials.By investigating and comparing relevant indicators such as phenology,growth traits,growth rate,and fruit traits,a membership function equation was established to comprehensively evaluate ten hybrid F 1 generation materials.The experimental results showed that,the fruit maturity period of hybrid F 1 generation was from August 13 th to 15 th,which was between Chinese seabuckthorn and Mongolian seabuckthorn.The average plant height of the test materials was 284.68 cm,the average crown width was 205.85 cm,and the average ground diameter was 5.47 cm.The growth traits of the hybrid seabuckthorn between China and Mongolia were significantly higher than those of the control varieties,namely female seabuckthorn and Chuyi seabuckthorn.They had the characteristics of strong tree power and fast growth rate.The average weight of fruit per hundred fruits was 30.33 g,and the weight of Russian large fruit seabuckthorn variety Chuyi per hundred fruits was significantly higher than other test materials.The lowest weight of female seabuckthorn per hundred fruits was 11.21 g.The average yield per plant was 8.28 kg,which was higher than that of the female parent Chuyi seabuckthorn and the control variety female of Chinese seabuckthorn.Among them,the Zhongmengza female 6 material had the highest yield per plant of 12.25 kg,while the female of Chinese seabuckthorn material had the lowest yield per plant of 2.43 kg.Through comprehensive evaluation,the E values of the two experimental materials,Zhongmengza female 6 and Zhongmengza female 10,were higher than those of other materials,and can be used as germplasm resources for preservation and promotion of mid maturity hybrid seabuckthorn cultivation.
