The highest marketable spikes (71111.11 per ha) was found in cultivar Aarti which might be due to its comparatively less deviation, during stress condition, from normal morphological and anatomical characteristics. The tolerant cultivars are those that can adapt to the change without much change in their normal growth. And the responses of those species are commercially acceptable that promote adaptation without compromising much with the plant growth and crop production. }, number = {32}, doi = {10.12944/CWE.10.2.36} }
