The multipurpose crop enset (Ensete ventricosum) has been traditionally cultivated in Ethiopia since ancient times. The main food product is the starch-rich fermented kocho made from the pseudostem and corm. There are many vegetatively propagated landraces utilised by farmers, but no concisions breeding have taken place, and there are requests for improved cultivars. There are also populations of wild ensets which propagate sexually, and the variation in characteristics among the wild is not studied. We suggest investigating the variation among the wild, in order utilise the most proper combinations of parent plants when breeding for different purposes. We analysed kocho, after 30 and 90days of fermentation, from three wild genotypes and three cultivars, to compare how and how much they differ in components and perceived food quality. The three cultivars scored generally higher than all the three wild genotypes for protein, fat, sugar and minerals, while the wild had larger fraction of starch. On average, panellists rated all the cultivated significantly higher than all the wild regarding the investigated characteristics (colour, texture, taste and overall). However, there were nine out of 25 panellists who rated at least one wild genotype higher or equal to at least one cultivar regarding taste, showing that people can be open for unfamiliar kocho. Therefore, we conclude that further investigations of the variation among wild plants should be done, aiming to get a larger gene pool with improved characteristics as e.g. disease tolerance or superior mineral uptake; by careful selection of parent plants, desired combinations can be achieved.
多功能作物埃塞俄比亚香蕉(Ensete ventricosum)自古以来就在埃塞俄比亚种植。其主要食品是由假茎和球茎制成的富含淀粉的发酵科乔。农民利用了许多通过营养繁殖的地方品种,但尚未进行精确的育种,人们要求培育改良品种。也有通过有性繁殖的野生埃塞俄比亚香蕉种群,但其野生种群之间的特征差异尚未得到研究。我们建议对野生种群的差异进行研究,以便在进行不同目的的育种时利用最合适的亲本组合。我们分析了三种野生基因型和三个品种的科乔在发酵30天和90天后的成分和感官食品质量,以比较它们在成分和感知食品质量方面的差异方式和程度。在蛋白质、脂肪、糖和矿物质方面,三个品种的得分普遍高于所有三种野生基因型,而野生品种的淀粉含量更高。平均而言,在调查的特征(颜色、质地、味道和总体评价)方面,评判员对所有栽培品种的评分均显著高于所有野生品种。然而,在25名评判员中,有9人在味道方面对至少一种野生基因型的评分高于或等于至少一种栽培品种,这表明人们可能会接受不熟悉的科乔。因此,我们得出结论,应该对野生植物的差异进行进一步研究,旨在获得具有改良特征(如抗病性或更高的矿物质吸收能力)的更大基因库;通过仔细选择亲本植物,可以实现所需的组合。
