Abstract:

Sorghum [Sorghum bicolor (L.) Moench] is one among the five major cereals of the world, being grown extensively in tropical and sub-tropical climate. In the present investigation six existing and recently released cultivars of Sorghum were taken to test their water stress tolerance. These cultivars are presently used extensively in the commercial production in Indian farmers. The pot trial was laid out in Factoral Completely Randomized Design with two replications involving with six genotypes viz., Phule Yashoda, Phule Revati, Phule Chitra, Phule Vasudha, Phule Anuradha and Phule Maulee and four moisture regimes (25%, 50%, 75% and > 90 % of field capacity). The effect of moisture stress was assessed using various physiological parameters. Among the six genotypes, the Phule Yashoda and Phule Revati showed significantly maximum mean chlorophyll a, b and total, RLWC, rate of photosynthesis, rate of transpiration, A-PAR, stomatal conductance and resistance at 25 % of F.C. It could be inferred that the genotype Phule Chitra and Phule Maulee are more suited under limited soil moisture condition (which moisture regime). While, the genotype RSV-1006 and Phule Yashoda found well suited for medium soil for stress as well as non-stress condition. Irrespective of moisture regime Phule Yashoda and RSV-1006 found to better than rest of genotypes based on physiological parameters. However, Phule Chitra and Phule Maulee had some physiological parameters which suited under water stress condition (M1). The resilience to drought shown by recent varieties is a good premise for their use in areas subjected to dry spells.
