Abstract
There are many research and review articles published on sweet sorghum. However, no single publication gives a detailed account of the morpho-biochemical traits of improved tropical sweet sorghum cultivars. This chapter gives detailed account of the materials used, methods followed for data collection and analysis to characterise sweet sorghum genotypes following the guidelines of Protection of Plant Varieties and Farmers Rights Act, 2001 (PPVFRA). The pooled analysis of variance for quantitative traits revealed that these cultivars had significant differences between them for the expression of all the quantitative characters under study for both the seasons. The results revealed that the productivity levels of tropical sweet sorghums during post-rainy season (October–March) are generally low due to photo-sensitivity and thermo-sensitivity of the genotypes vis-a-vis that of rainy season (June–October) and necessitates identifying new sources/alleles contributing to both biomass and sugar yield.
The chapter is discussed under three sections, i.e. materials, data collection, result and discussion.
