A stratified random sample of 180 soybean land races from Hu'nan,Guangdong,GuangXi and Yunnan in Southern China was tested in Nanjing to study their genetic peculiarity variability and selection potential of agronomic and seed quality traits.The population appeared to have higher plant height,smaller 100-seed weight,higher protein content,lower oil content,and lower seed yield than the commercialcultivars from lowed Yangtze Valley.The land races from the four provinces were different in most traitsstudied.Days to flowering,days to maturity,number of pods per plant,100-seed weight and seed yield hadcomparatively great selection potential while oil content and protein content had only a moderate selectionrespones.The principal component analysis,dynamic clustering analysis and correlation analysis amongagronomic and seed quality traits of the population were also reported.

在南京夏播条件下,研究华南四省区大豆地方品种群体主要农艺和品质性状的遗传特点、选择潜力和性状相关、华南群体具有植株高、粒小、蛋白质含量高、油分含量低、产量低等特点。百粒重、产量遗传变异丰富,选择潜力大;品质性状遗传变异小,选择潜力有限。全生育期是遗传变异中的最主要成分性状,且以全生育期进行的动态聚类分析分成的三类,有按春、夏、秋(冬)品种自然分类的趋势.产量与蛋白质含量负相关,与油分含量无显著相关;蛋白质含量与油分含量无显著相关。

Sugarcane is probably the most genetically complex crop for which genome mapping has been attempted since they are polyploid clones derived from interspecific hybridization between two species, S. officinarum (2n=80) and S. spontanoum (2n=40-128).Cultivars have different chromosome numbers,ranging from 100-130 with about 5- 10 % of them contributed by the former and the rest by the later. Due to such genetic peculiarities,it had been believed that molecular markers can not be applied to sugarcane as they are to most other plants. Some sugar-producing nations invested in molecular marker research in recent years,and make considerable progress. This paper described the principle, main charcteristics and use potence of molecular marker in crop, and reviwed its research progess. The auther analysised present problems and evaluated research prospects in sugarcane.

甘蔗是遗传上最为复杂的作物,它主要是由热带种(2n=80)、割手密(2n=40-128)等种间杂交而来。甘蔗的染色体数很多,在100-130条之间。其中,有5-10%的染色体来自割手密,其余主要来自热带种。由于这种特殊性,人们曾经认为甘蔗不能象其它作物那样进行分子作图。近年来,由于一些主要产糖国联合投入巨资开展这方面的研究,现已取得一些突破性进展。本文简要叙述分子标记的主要原理、特点以及在作物遗传育种上的应用潜势,阐述分子标记在甘蔗上的研究进展,指出甘蔗分子标记研究存在的一些问题和今后的研究方向,并对今后进一步研究提出自己的设想。

In order to success in common maize breeding,it is keys to pay highly attention to creating of germplasm and introducing into exotic germplasm.So germplasm base can be abundance and the genetic variety can be reserved.Material of breeding must be elected carefully according to different types,which genetic peculiarity can be maintained.For the purpose of breeding, high combining a bility, high yield and high resistant inbred line maize. The breeding objective are as follows:vertical leaf,large ears,good quality,high yield,early riping and multiple resistance.Electing parents should be defined in types of high heterosis according to five types, which qualitative character of parents should be make up each other and quantitative character should be closed to breeding object with best possibility.New parental combination should be observed in field repeatly,and be careful to cut down in the term of breeding due to break with convention.It should be thought highly of the improvement of the horizontal resistance,tolerance of large dense and lodging-resistance.And,this paper studied other breeding problems too.

高度重视种质创新和外源种质导入 ,丰富种质基础 ,保持遗传多样性 ,是搞好普通玉米育种之关键。要选育高配合力、高产、高抗的玉米自交系 ,按类群精选素材 ,保持其遗传特点。育种目标应是“竖叶、大穗、优质、高产、早熟、多抗”。按 5大类群在强杂交优势类群间选配亲本 ,质量性状要求双亲互补 ,数量性状双亲应尽可能接近育种目标。对新组合在田间要反复观察 ,慎重“破格升级” ,缩短育种年限。重视其水平抗性、耐密性及抗倒性的提高 ,并对其它育种问题作了研讨
