Description: A total number of 100 genetically and phenotypically diverse genotypes were collected from Cotton Research Centre, Mahigang Rangpur. The genotypes were evaluated at Cotton Research, Training and Seed Multiplication Farm, Sadarpur, Dinajpur during 2021-2022. There were three sowing dates such as, 15 June 2021, 1 July 2021 and 15 July 2021, along with a trial which was conducted under rainfed condition sown on 15 July 2021, the spacing was 40 cm x 90 cm and unit plot size was 4 m x 4.5 m accommodated 50 plants with three replications. Data were recorded on plant height (cm), sympodial branches/plant, bolls/plant, days to 50% flowering, days to 1st boll picking, earliness index, single boll weight (g), phenotypic acceptability, seed cotton yield/plant and lint fiber yield/plant. Over the three sowing dates, 45 early boll picking genotypes were selected and the range of seed cotton yield was 115.94-128.54 g. Of the three sowing dates 1 July was ideal for cotton cultivation in northern part of Bangladesh since higher seed cotton yield with high phenotypic acceptability were measured from the genotypes sown on that day. Further, under rainfed condition, 30 drought tolerant genotypes were identified based on proline content (µ mol/g), chlorophyll content (n mol/g), relative leaf water content, excise leaf water loss and seed cotton yield/plant. Under drought situation the seed cotton yield ranged from 105.24-112.92g. Generally the potential of the genotypes was lower in rainfed condition compared to optimum condition. The physiological traits were positively correlated with seed cotton yield/plant. However, among the four traits, proline content and chlorophyll content appeared as the most influential to achieve high seed cotton yield under drought condition. The range of proline content ranged from 0.20- 0.95 µ mol/g and the highest proline was estimated from BC 0042, on the other hand the chlorophyll content ranged from 31.82-40.95 n mol/g and maximum chlorophyll was measured in Mutant-1. Not only that these two traits were positively and significantly associated with the other two physiological traits. Plant having shorter in height seemed to drought tolerance since these genotypes occupy maximum ground coverage to reduce evapotranspiration. None of the genotypes showed resistant to insect attack but degree of infestation varied from genotypes to genotypes. Since the identified drought tolerant 30 genotypes also included in the early boll picking cluster, hence after authentication by phenotypic platforming and molecular analysis the suitable genotypes might be obtained which would possess both early harvesting and drought tolerant properties, essentially needed for the cotton growers in the northern belt of Bangladesh.
