Abstract:
This study was conducted in the Agricultural Research Corporation, ARC at
Gezira Research Station, Gezira State, Wad Medani, Sudan. The objective of this
study was to evaluate ten Egyptian cotton lines for yield, quality and bacterial
blight resistance. Significant differences were recorded for earliness of maturity
and boll weight and high significant differences were also recorded for weight of
lint per boll, seed cotton yield, disease severity, plant height, number of bolls per
plant and number of monopodia per plant. No significant differences were observed
among genotype for: ginning out-turn, seed index , number of seeds per boll,
weight of seed cotton per boll, disease incidence and number of sympodia per
plant. The results indicated that 94-B-2 experimental line has an average seed
cotton
yield advantage of 19% over 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 a 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, less vulnerability to bacterial blight, higher GOT and
better fiber characteristics overwhelming the commercial cotton cultivar Barakat-
