Drought stress is a major factor limiting crop production. Genetic improvement is possible in cotton and other crops against drought stress by molecular breeding. A drought tolerant (B-557) and a drought susceptible (FH-1000) cultivar were crossed to develop F2 population. The parents and the F2 population were studied under osmotic stress in hydroponic culture. A survey of 524 SSR and EST-SSR primers revealed a lot of DNA polymorphism between the drought resistant and drought susceptible cultivar.

Identification of drought-responsive genes in a drought tolerant cotton (Gossypium hirsutum L.) cultivar under reduced irrigation field conditions and development of candidate gene markers for drought tolerance

Cotton productivity is affected by water deficit,  and little is known about the molecular basis of drought tolerance in cotton. In this study, microarray analysis was conducted to identify drought-responsive genes in the third topmost leaves of the field-grown drought- tolerant cotton (Gossypium hirsutum L.) cultivar Acala 1517-99 under drought stress conditions. Water stress was imposed by withholding irrigation for 9 days in the early squaring stage, which resulted in 10–15 % reduction in plant growth compared to the well-watered plants.

A comprehensive meta QTL analysis for fiber quality, yield, yield related and morphological traits, drought tolerance, and disease resistance in tetraploid cotton

The  study  of  quantitative  trait  loci  (QTL)  in  cotton (Gossypium spp.) is focused on traits of agricultural significance. Previous studies have identified a plethora of QTL attributed to fiber quality, disease and pest resistance, branch number, seed quality and yield and yield related traits, drought tolerance, and morphological traits.

Inducing Drought Tolerance in Upland Cotton (Gossypium hirsutum L.), Accomplishments and Future Prospects

Cotton (Gossypium hirsutum L.) is dreadfully drought sensitive crop causing incentive reduction in yield. Although conventional breeding has been successful in the past in developing drought tolerant cotton cultivars by modifying the morphological and physiological traits, yet the approach is time consuming and labor intensive. Furthermore the polygenic nature of drought tolerance slows the progress.

QTL mapping for physiology, yield and plant architecture traits in cotton (Gossypium hirsutum L.) grown under well-watered versus water-stress conditions

Increasing scarcity of irrigation water is a major threat to sustainable production of  cotton  (Gossypium hirsutum L.). Identifying genomic regions contributing to abiotic stress tolerance will help develop cotton cultivars suitable for water-limited regions through molecular marker-assisted breeding
