Evaluation of breeding potential of introgression lines developed from inter-specific crossing between upland cotton (Gossypium hirsutum) and Gossypium barbadense

Published on

Interspecific crosses were attempted between Suraj (G.
Hirsutum) and Suvin (G. Barbadense) in order to introgress
fibre quality genes in elite genotypes of upland cotton. The
results of 201BC
1F4 individual single plant selections of 19
progenies indicated that the average values of introgression
lines for all the yield components except boll number had
higher values than the parental gentotypes. The ginning
percentage (40.9-47.2%), boll weight (2.5-8.4g) and fibre
strength (21.6-31.2 g/tex) indicated genetic improvement
of the traits. BC
1F4 progenies SPS 32-94, SPS 33-94, SPS 39-
94, SPS 45-31, SPS 46-31, SPS 48-31, SPS 49-31 and SPS 50-
31 were found to be promising for use in cotton breeding
programme.
