Abstract:
The dataset extensively examines the factors considered when choosing sweet potato genotypes, considering various characteristics. Notably, Moz1.15 demonstrated the highest marketable root yield at 46.46 t/ha, H5.ej.10 exhibited the highest beta-carotene level at 48.94 mg/100 g, and Moz1.9 recorded the highest vitamin C content at 23.89 mg/100 g. Moreover, there were significant correlations (ranging from 0.21 to 0.84) among the yield and quality traits studied in sweet potatoes. Principal component analysis (PCA) confirmed the connections among these traits, identifying four distinct clusters of genotypes, each characterized by specific significant combinations of traits. Factor analysis using the multi-trait genotype-ideotype index (MGIDI) highlighted the considerable impact of sweet potato traits across two growing seasons (2020-21 and 2021-22), facilitating the selection of genotypes with potential genetic gains ranging from 1.86 % to 75.4 %. Broad-sense heritability (h2) varied from 64.9 % to 99.8 %. The use of the MGIDI index pinpointed several promising genotypes, with BARI Mistialu-12 and H9.7.12 consistently performing well over both years. These genotypes exhibited both strengths and weaknesses.
摘要:
该数据集广泛检查了选择甘薯基因型时考虑的因素,考虑到各种特点。值得注意的是,Moz1.15表现出最高的可销售根系产量,为46.46吨/公顷,H5.ej.10表现出最高的β-胡萝卜素水平,为48.94毫克/100克,Moz1.9记录了最高的维生素C含量,为23.89mg/100g。此外,在甘薯中研究的产量和品质性状之间存在显着相关性(从0.21到0.84)。主成分分析(PCA)证实了这些性状之间的联系,确定四个不同的基因型簇,每种特征都具有特定的显著性状组合。使用多性状基因型-理想型指数(MGIDI)的因子分析强调了甘薯性状在两个生长季节(2020-21和2021-22)的显着影响。促进选择潜在遗传增益为1.86%至75.4%的基因型。广义遗传力(h2)从64.9%到99.8%不等。MGIDI指数的使用确定了几种有希望的基因型,BARIMistialu-12和H9.7.12在这两年中一直表现良好。这些基因型表现出优点和缺点。
