Evaluation of single cross multiple cross and modified back cross methods based on recombination and character association in upland cotton

Evaluation of single cross multiple cross and modified back cross methods based on recombination and character association in upland cotton

Indian Journal of Agricultural Sciences 57(5): 318-321

Of the single-cross, multiple-cross and modified back-cross methods used for increasing the desirable recombinations and character associations in 6 varieties, viz. 'G. Cot. 10', 'MCU 5', 'Buri 1007', 'Acala 4-42', 'AC 738' and 'Bhagya Laxmi', of upland cotton (Gossypium hirsutum Linn.), multiple-cross method proved to be efficient in producing proportion (13.3%) of strains which showed recombinations for yield, ginning outturn and halo length. The multiple-cross method was also effective in weakening negative correlation between yield and fibre strength, whereas single-cross and modified back-cross methods were useful in breaking linkages between yield and fibre length. Modified back-cross method succeeded in breaking close and negative association between ginning outturn and fibre characters, viz. fibre length and fibre strength. For creating a higher proportion of strains with desirable characters, multiple-crossing method would be ideal, while for effective breaking of character associations modified back-cross method would be more useful.
