Abstract

This study evaluated the chemical composition of pearl millet seeds belonging to different genotypes by biplot analysis. Seeds of 26 different pearl millet populations obtained from ICRISAT (International Crops Research Institute for the Semi-Arid Tropics) within the scope of TÜBİTAK 219O103 run by Şırnak University were used. The seeds were ground and analyzed for their chemical composition, i.e., acid detergent fiber (ADF), neutral detergent fiber (NDF), crude protein (CP), digestible dry matter (DDM) and dry matter intake (DMI) rate. The results revealed that crude protein ratio varied between 11.74-19.24%, whereas ADF ratio differed between 3.44-11.43%. Similarly, NDF ratio varied between 10.23-23.47%, while DDM ratio ranged between 79.98-86.21%. Likewise, DMI ratio differed between 5.11-11.72%. Scatter plot obtained after biplot analysis indicated three different groups based on the analyzed traits. The first group contained DDM and DMI, whereas the second group consisted of ADF and NDF. The protein ratio was in the third group. It was determined that ADF-NDF and DMI-DDM properties were negatively correlated with each other. According to biplot, genotypes ‘A5-13’, ‘A13-6’ and ‘B1-7’ were prominent for ADF -NDF, DMI-DDM, and protein ratio, respectively. Therefore, these genotypes can be used in future studies to induce the desired traits.

双图法分析珍珠粟基因型种子营养成分的遗传变异

采用双图分析方法对不同基因型珍珠粟种子的化学成分进行了分析。使用了Şırnak大学主办的TÜBİTAK 219O103项目范围内从ICRISAT(国际半干旱热带作物研究所)获得的26个不同珍珠粟种群的种子。将种子磨碎，分析其化学成分，即酸性洗涤纤维(ADF)、中性洗涤纤维(NDF)、粗蛋白质(CP)、可消化干物质(DDM)和干物质采食量(DMI)率。结果表明，粗蛋白质比值为11.74 ~ 19.24%，ADF比值为3.44 ~ 11.43%。同样，NDF比率在10.23 ~ 23.47%之间，DDM比率在79.98 ~ 86.21%之间。DMI比值也在5.11 ~ 11.72%之间。双图分析后得到的散点图根据所分析性状划分为3个不同的类群。第一组含有DDM和DMI，第二组含有ADF和NDF。蛋白质比例为第三组。结果表明，ADF-NDF和DMI-DDM的性质呈负相关。双标图显示，ADF -NDF、DMI-DDM和蛋白比基因型分别为A5-13、A13-6和B1-7。因此，这些基因型可以在未来的研究中用于诱导所需的性状。
