Path analysis in the evaluation of ethanol and culm yield components in sweet sorghum

ABSTRACT Path analysis is a methodology able of splitting the correlation coefficients into direct and indirect effects, helping breeder in study quantitative traits. This aimed to use path quantify such effects on yield theoretical ethanol, exerted by variables total culm dry matter yield, soluble solids content at harvest efficiency broth extraction, agronomic average plant height harvest, number days until flowering, green percentage culms yield. The variable presented greatest (0.8844) (0.5969) indicating great dependence main explanatory variable. largest effect was via (0.2820). four considered as dependent (average height, yield) showed positive values for (0.8010)
