Abstract: Desi cotton or herbaceum cotton improvement programme mainly for long linted (>27.5 mm) genotypes play perfect balancing role in cotton cultivation with low input, best quality and sustainable utilization of natural resources. The present investigation involve 220 advanced breeding lines of F5 generation which were selected mainly for yield, fiber quality and G. herbaceum type characters in every step of segregating generation obtained through interspecific cross of parents GVhv 585 and 824. All entries were evaluated in augmented design with four checks. Entry F5-214/220 has recorded significantly higher lint yield of 157.1 gm/plant followed by F5-146/220 (128.6 gm/plant) and F5-187/220 (128.1 gm/plant) over the best check GADC-2 (53.8 gm/plant). The range of fiber length was observed between 21.5 mm (F5-102/220) to 33.1 mm (F5-140/220). Highest bundle strength was recorded with Entry F5-143/220 (34.6 g/tex) and least strength with entry F5-214/220 (20.7 g/tex). The range of GOT % was recorded between 20.7 % (F5-195/220) to 43.8 % (F5-156/220). Promising entries F5-23/220 and F5-178/220 produced seed cotton yield (298.2 g/plant, 122.7 g/plant) and also recorded good fiber length (29.5 mm, 30.2 mm) and bundle strength (29.2 g/tex, 28.8 g/tex), respectively.
