Research and Application of Multivariate Genetic Analysis in the Field of Crop ...

着重阐明了它在作物遗传育种领域中的地位和作用，并对存在的问题作了讨论。

Therefore, it is a Herculean and long-term task for plant breeding workers to cultivate the germplasms of resistance to these factors.

因此，培育抗病、抗虫和抗逆的作物品种是育种工作者长期而艰巨的任务。

We discusses that the imperativeness and feasibility as well necessity of developing high water use efficiency agriculture in china at these aspects: security of grain and economy and water resource, agriculture resource in North and South of China, regulating agriculture structure, agronomic methods for drought resistance and water saving, crop high yield breeding and high efficiency water resource management.

从粮食安全和经济安全及水安全，南北方农业资源，农业结构调整，农艺抗旱节水措施，作物高产育种，高效的水管理体系等方面，论述了发展高水效农业发展的迫切性、可行性和必然性。

However sugarcane is a nonsexual propagation crop with highly ployploidy and complex genetic background,breeding pathogens-resistance cultivals by using traditoonal breeding techniques will be a formidable task.

但由于甘蔗是高度杂合、遗传背景复杂的无性繁殖作物，常规的抗病育种所需时间较长，盲目性大，效果也有限制。

Because of heavy heterozygosity of cassava genome caused by stack propagation and outcross in longtime, the practice of biotechnology would resolve these problems in broad background.

由于木薯是无性繁殖的异花授粉作物，传统育种方法在基因重组方面受到局限；生物技术的应用却能够在很大程度上解决上述问题。

Molecular tagging new three genes with bulked segregant method.

作物遗传育种依赖于新基因的发掘和利用，其中基因定位和紧密连锁的分子标。。。

From differentiation of soybean varieties and photoperiod adjustment, anatomical differentiation essence of different types of stem termination soybean varieties, variation law of stem termination development under different photoperiod treatments, effect of long day on the terminal raceme of soybean, regulation rules of AGAMOUS gene among different soybean varieties and under different photoperiod treatments were studied, which would provide theory base of plant type breeding of soybean especially improvement of podding-habits and cultivation and management of soybean.

因此，试验于2006和2007年在中国农业科学院作物科学研究所完成，主要从大豆的品种差异和光周期调控入手，利用解剖学和分子生物学技术，研究不同结荚习性大豆品种的本质差异、大豆在不同光周期处理下茎顶的变化规律，进一步明确长日照对大豆顶端花序的影响，及AGAMOUS基因在不同光周期处理下大豆品种中的表达规律，为大豆株型育种特别是结荚习性的改良及大豆栽培管理提供理论依据。

This study provided theoretical and technical basis for obtaining virus-resistant plants by modern molecular biology and plant genetic engineering, and technical platform for gene transformation in mustard and Cruciferae as well.

本研究不仅为利用现代病毒分子生物学和植物基因工程育种获得抗病毒农作物提供理论和技术依据，也为芥菜以及其他十字花科作物转基因技术提供技术平台。
