Growth analysis of several sorghum hybrids and improved cultivars was carried out to assess the progress made in varietal improvement. Compared to CSH-1, the first commercial hybrid, the performance of improved varieties like SPV-22J and SPV-3J4 was superior, but much headway needs to be made before attaining performance levels of CHS-5 or CSH-9. At comparable heights and maturities, improvement in total biomass production with out detriment to harvest index leads to higher order yields. There are indications that marked yield superiority and stability of performance may be positively related but more critical studies are needd to establish this.
