摘要

在2000/2001年旱收期间，在南马托格罗索州联邦大学杜拉多斯校区农业科学中心对16种常见的豆类基因型、商业品种和先进品系进行了评估。估计了控制形态生理性状和产量成分的遗传和表型参数。这些参数是在植物水平上估计的。在随机完全区组实验中获得基因型之间、基因型内部和小区水平的方差估计。每个基因型有3个重复用于计算。所研究群体的所有性状都具有广泛的遗传变异，其中主茎长是最有希望选择的性状，而成熟期是最没有希望选择的性状。小区水平分析的精度高于植株水平分析。

Estimates of genetic parameters in common bean genotypes

Sixteen common bean genotypes, commercial varieties and advanced lines, were assessed at the Nucleus of Agrarian Sciences at the Federal University of Mato Grosso do Sul, Dourados campus, in the 'dryharvest 2000/2001. Genetic and phenotypic parameters in control of morpho-physiological traits and yield components were estimated. These parameters were estimated at plant level. Variance estimates between and within genotypes and at plot level were obtained in randomized complete block experiments. Three replicates of each genotype were available for the calculations. The populations under study had wide genetic variability for all the traits studied whereas the main stem length was the most promising trait for selection and days to maturity was the least promising. The plot level analysis showed greater precision than plant level analysis.

期刊介绍： The CBAB – CROP BREEDING AND APPLIED BIOTECHNOLOGY (ISSN 1984-7033) – is the official quarterly journal of the Brazilian Society of Plant Breeding, abbreviated CROP BREED APPL BIOTECHNOL. It publishes original scientific articles, which contribute to the scientific and technological development of plant breeding and agriculture. Articles should be to do with basic and applied research on improvement of perennial and annual plants, within the fields of genetics, conservation of germplasm, biotechnology, genomics, cytogenetics, experimental statistics, seeds, food quality, biotic and abiotic stress, and correlated areas. The article must be unpublished. Simultaneous submitting to another periodical is ruled out. Authors are held solely responsible for the opinions and ideas expressed, which do not necessarily reflect the view of the Editorial board. However, the Editorial board reserves the right to suggest or ask for any modifications required. The journal adopts the Ithenticate software for identification of plagiarism.
