- 摘要:
- 为合理利用芫荽种质资源，该研究以96份芫荽种质为材料，采用形态学标记评价芫荽种质的遗传多样性，并对芫荽19个生物学性状进行分析。结果表明：抽薹天数与始花期、终花期、收获天数、基生叶数、基生叶长、株高、植株生叶状态、分枝数均呈极显著正相关，基生叶数与最长基生叶长、基生叶形、植株有叶状态、植株分枝数均呈极显著正相关，最长基生叶长与株高呈极显著正相关，抽薹天数及基生叶数均与千粒重呈负相关。在遗传距离6.40处将96份种质分为5类。
- Abstract:
- In order to make efficient use of coriander germplasm resources,morphological markers of 96 accessions of coriander were conducted to evaluate their level of genetic diversity. The correlation of 19 biological characters of 96 coriander germplasm was analyzed and all the germplasm were analyzed by systematic cluster. The results showed that，number of days until stem elogation(DSE) was positively correlated with number of days until start of flowering(DSF)，number of days until end of flowering(DEF)，number of days until harvesting(DH)，number of basal leaves(NBL)，length of the longest basal leaf(LLBL)，plant height (PH)，leafiness of the plant(LP)，number of branches(NB).number of basal leaves(NBL) was positively correlated with length of the longest basal leaf(LLBL),blade shape of the longest basal leaf(BSBL),leafiness of the plant(LP),number of branches(NB).Length of the longest basal leaf(LLBL) was positively correlated with plant height (PH).Number of days until stem elogation(DSE) and number of basal leaves(NBL) were negatively correlated with weight of 1 000 fruits(W1 000F).The germplasm could be divided into five categories at the genetic distance 640.
