Solanum aethiopicum L. is a nutrient dense African indigenous vegetable. However, advancement of its improved varieties that can increase productivity, household income, and food security has not been prioritized. Further still, studies on some of the crops that have been worked have indicated that it is not a guarantee that the improved varieties will be accepted by the end users and therefore there is need to identify and profile what genotypes are of interest to farmers and their preferred traits through inclusive participatory evaluations. Farmer participatory evaluations were conducted to profile farmers’ traits of interest and preferred genotypes. A total of 24 genotypes were established in three replications in 6 farms in 3 districts; Wakiso, Mukono, and Luwero as these are the major producing districts of the vegetable in Uganda. A total of 177 sex-disaggregated farmers were engaged in scoring the genotypes for pest, disease and drought tolerance, general appeal, leaf yield, leaf texture, and seed yield for best 10 genotypes under each variable. Non-significant differences in trait (p > 0.05) and genotype preferences (p > 0.05) were obtained between men and women. The most desired farmer traits were seed and leaf yield, followed by pest and disease resistance. The overall preferred genotype in terms of disease and pest resistance, leaf yield, leaf texture, and seed yield were E12 followed by E11. Gender does not seem to influence farmer choices for the S. aethiopicum, Shum group, indicating an opportunity for single variety prototype advancement by breeders and dissemination by seed companies.

农民对埃塞俄比亚茄 (Solanum aethiopicum L.) Shum 组的偏好性状和基因型选择

Solanum aethiopicum L. 是一种营养丰富的非洲本土蔬菜。然而,能够提高生产力、家庭收入和粮食安全的改良品种的推广并未得到优先考虑。此外,对一些已种植作物的研究表明,并不能保证改良品种会被最终用户接受,因此需要确定和分析农民及其农民感兴趣的基因型。通过包容性参与性评估来选择偏好的特征。进行了农民参与性评估,以了解农民感兴趣的性状和偏好的基因型。在 3 个地区 6 个农场的 3 个重复中建立了总共 24 个基因型;瓦基索、穆科诺和卢韦罗是乌干达蔬菜的主要产区。共有 177 名按性别分类的农民对每个变量下最佳 10 个基因型的害虫、疾病和干旱耐受性、一般吸引力、叶子产量、叶子质地和种子产量的基因型进行了评分。男性和女性之间的性状(p > 0.05)和基因型偏好(p > 0.05)没有显着差异。农民最期望的性状是种子和叶子的产量,其次是抗病虫害能力。就病虫害抗性、叶产量、叶质地和种子产量而言,总体首选基因型是 E12,其次是 E11。性别似乎并不影响农民对 S. aethiopicum、Shum 组的选择,这表明育种者有机会改进单一品种原型并由种子公司传播。
