Applying AMMI model to analyse the root production, sugar production and sugar stability of six sugar beet varieties, and these three value and the corresponding value of the species stability parameters as an indicator, the tested varieties are evaluation.

应用AMMI模型对6个甜菜品种的块根产量、含糖率和产量糖进行稳定性分析，并以这3个性状的表型值和相应的品种稳定性参数为指标，综合评价供试品种。

Based on the study of 120 cultivated herbaceous peonies and 8 wild species native to China, the relationship among them was firstly investigated, and the result indicated that 4 narrowly-distributed wild species involving Paeonia sinjiangensis K. Y. Pan, P. anomala L., P. emodi Wallich ex Royle and P. sterniana Fletcher have no chance to be the ancestor of Chinese cultivated herbaceous peonies. Then the difference and similarity existed in the root, leaves and flowers of the wild species and cultivars was exhaustively compared and it is concluded by the equivalent affinity between P. lactiflora Pall. and the cultivars.

以原产我国的120个栽培品种和8个野生种为主要研究对象，首先根据地理分布的差异对栽培芍药与各个野生种的亲疏关系进行了分析探讨，表明新疆芍药、块根芍药、多花芍药和白花芍药等4个窄布种不可能参与我国芍药品种的栽培起源；然后对栽培品种和各野生种之间的根、叶及花等性状的差异进行了细致的比较分析，进一步证明川赤芍亦不可能参与我国栽培芍药品种的起源，草芍药和美丽芍药等2个种对我国栽培芍药的起源影响甚微。

Food plant (Ipomoea batatas; family Convolvulaceae) native to tropical America and widely cultivated in tropical and warm temperate climates.

旋花科植物，学名为Ipomoea batatas，块根可食。原产于热带美洲，广泛栽培于热带及暖温带地区

At a glance of the molecular mechanism, one gene encoding 218 amino acids was identified from cDNA-AFLP differential study and then named as Ipomoea batatas MADS-box 1 gene (IbMADS1) based on earlier studies. From sequence alignment and phylogenic analysis, IbMADS1 exhibited a typical type II-MIKC structure, including two conserve domains, MADS-box and K-box.

本论文针对从甘薯块根筛选出的MADS-box基因，IbMADS1（Ipomoea batatas MADS-box gene 1）进行分析，分别探讨该基因在甘薯各部位的表现方式、受植物荷尔蒙调节的影响，以及甘薯属中野生亲缘种间的基因表现歧异性，再进一步从转殖植物的外表形态了解此基因可能的生理功能。
