| 摘 要： | 对芦笋的6个农艺学性状指标进行相关性分析,并对产量和一级笋率进行了多重比较。结果表明,影响芦笋产量的重要因子有茎粗、株高和茎数。影响芦笋一级笋率的重要因子有茎粗、株高、产量。植株越高,产量越高,一级笋率也越高。茎粗、株高、茎数构成芦笋产量、品质特性,同时也是新品种选育的必备性状。通过对产量和一级笋率的多重比较发现,全雄品种在产量、一级笋率和其它农艺性状方面明显优于其它常规种,因此芦笋全雄品种的选育已成为目前芦笋育种的重中之重。

| Abstract: | We analyzed 6 asparagus agronomic characters and did multiple comparison to the asparagus yield and first-class asparagus spears ratio. The result showed that the important factors of influencing asparagus yield were as followed the stem diameter, the plant height and the number of stem; the important factors of influencing the first-class asparagus spears ration were as followed the stem diameter, the plant height and the yield. The plant height was higher and the yield was higher, at the same time the first-class asparagus spears ratio was also higher. The stem diameter, the plant height and the number of stem constituted the asparagus yield and the quality characteristic. At the same time it was also necessary for selecting the new varieties. We found that the all-male varieties were superior to the others in the yield and the first-class asparagus spears ratio through the multiple comparison of the yield and the first-class asparagus spears ratio. So the selection of the all-male varieties has become the work key. |
