Introgression of fiber traits of Gossypium barbadense L. into Gossypium hirsutum L.

Published on

2 of cotton hybrid DCH-32 was forwarded to F3 as a
bulk by taking 10 seeds per plant; similarly two seeds
from each F3 plants were taken to constitute F
4 generation.
Selection in F
4 generation was carriedout. Measurement
of halo length was used as base for selection of plants.
As many as 184 plants were selected. On detail
investigation of fibre traits, plants with >23 g/tex fibre
strength, 30 mm fibre length (2.5% SL) and around 4
micronnaire value have been isolated. Selected platns
were tested in F
s generation in plant to row progeny,
plants with higher fibre strength (>23 g/tex) have been
recovered; however micronaire of these platns was around
2.8. Finally the selected plants tested in Fe have been
recorded for seed cotton yield, ginning outturn and fibre
properties. Desirable plants having higher seed cotton
yield than DS-28 (38 g/plant) with high fibre strength (>23
gltex) have been recovered, however, the micronaire of
these plants is around 2.8
