Impact of Different Plant Canopy Traits on Sorghum Yields

Studying changes in plant canopy can help to improve architecture and increase yields. Specifically, for sorghum (Sorghum bicolor L.), characterizing identifying relevant traits be helpful not only its productivity but better fit this crop the rotation from a system perspective. With purpose, morphological characteristics of 20 hybrids were measured during 2022 growing season Wamego, KS, U.S. (United States). The most examined leaf angle area at leaf- canopy-level (leaf index, LAI), all determined different points growth cycle (seventh-leaf, V7, flowering, physiological maturity). Furthermore, duration vegetative reproductive phases also recorded as days maturity. A conditional decision tree analysis was employed cluster according their variation impact on yield. In summary, end LAI (at maturity) one group it accounted ~70% variation. Hybrids with high V7 low maturity, addition longer time presented greater These findings lead future investigation using same under climatic conditions.
