Evaluation of Some Promising Cotton Genotypes and Commercial Variety for Yield, Quality and Bacterial Blight Resistance

Abstract

Ten cotton genotypes were evaluated (Gossypium Barbadense L) for seed cotton yield, better quality and bacterial blight resistance. in the Agricultural Research Corporation, ARC at the Gezira Research Station, Gezira State, Wad Medani, Sudan.in seasons 2012/2013 and 2013/2014, The experiment was laid in a randomized complete block design (RCBD) with four replications. The results indicated that 94-B-2 line has an average seed cotton yield advantage of 19% over Barakat-90, mean seed cotton yield 2219 compare to 1868 for Barakat-90, with fiber length of 35.1, micronaire value of 3.7 and fiber strength of 37.5 better than Barakat-90. It gave 52% of its yield in the first pick compared to 44 for Barakat-90. It has a GOT of 34% compared to 32.6 for Barakat-90. It recorded disease incidence and disease severity of 0.58 and 38.8%, respectively compared to 0.72 and 51.8 for Barakat-90. Hence this line emerged as a new candidate with new traits: higher seed cotton yield, earliness of maturity, resistance to bacterial blight, higher GOT and better fiber characteristics is better than the commercial cotton cultivar Barakat-90.
