摘要

The present investigation was undertaken to estimate various genetic parameters for some agronomic traits of introduced Ethiopian mustard (Brassica carinata A. Brun) genotypes. The experiment was laid out in randomized complete block design with three replications at Holetta Research Center, Ethiopia. Analysis of variance showed significance difference among the genotypes for traits studied except plant height and seed yield. Phenotypic Coefficient of Variation (PCV) and Genotypic Coefficient of Variation (GCV) ranged from 1.2-10.2% and 1.9-6.8%, respectively. The highest heritability values was shown by oil content (99.8%) followed by days to flowering (96.5%) and days to maturity (89.1%). High heritability along with high genetic advance (as percent of mean) was recorded for days to flowering and oil content. Days to flowering, days to maturity and oil content are important traits to be considered for further variety development program.Digital Object Identifier http://dx.doi.org/10.3923/ijar.2012.160.165

Brun)基因型一些农艺性状的各种遗传参数。该实验在埃塞俄比亚Holetta研究中心进行了三组重复的随机完整区组设计。方差分析显示,除了株高和种子产量外,所研究性状的基因型之间存在显着差异。表型变异系数(PCV)和基因型变异系数(GCV)分别为1.2-10.2%和1.9-6.8%。最高的遗传力值由含油量(99.8%),紧随开花的天数(96.5%)和至成熟的天数(89.1%)表示。记录到开花和含油量的天数都显示出高遗传力和高遗传进展(以平均百分比表示)。开花天数,成熟天数和含油量是进一步品种开发计划要考虑的重要特征。数字对象标识符http://dx.doi.org/10.3923/ijar.2012.160.165
