Title: Levant cotton – for changing climate to conserve water and environment

Abstract: Climate change has become common phenomenon now a day were we are noticing low rainfall, drought situations, soil salinity and high temperature for this changing climate situations breeding of field crops is an very challenging issue. In this line of ray an attempt was made to improve the seed cotton yields and fiber quality traits in levant cotton using gamma rays and simple hybridization techniques. Since, levant cottons have deeper root system they can sustain long dry spells and have the capacity to grow in saline and sodic soils and also it is very essential to get rid of the harmful chemicals required to control many pest and diseases, which would be beneficial for both human and environmental health as levant cottons are inherently tolerant to pest and diseases. It is this resilience to tough biotic and abiotic conditions that makes levant cottons the right choice for sustainable farming. These levant cottons have shorter and coarse fiber, which are suitable for absorbent cotton/surgical cotton, denims, mattresses and technical textiles, whose demand is growing and in present day markets they are fetching 20 per cent extra amount than that of the American cotton. In the present study total of 61 progeny lines along with 5 parents were evaluated at Agricultural Research Station, Dharwad. The line S22 (Jayadhar X MDL-2582 irradiated) has recorded higher seed cotton yield of 749 kg/ha and good boll weight of 1.6 g as compared to check parent Jayadhar with 493 kg/ha and boll weight of 1.3 g, while fiber length of S22 line was 21.6 mm, bundle strength was 21.5 g/tex and micronare (6.3) compared to check jayadhar (20.8 mm, 21.6 g/tex and 6.1). The results indicated that hybridization followed by irradiation has created additional variation.
