Genetics of fibre elongation

The present study from the cross (FL × Fl) an attempt was made to understand the variation for number of fibres per unit area in segregating F2 population besides genetics of fibre elongation.

The present investigation was performed with fifty-three genotypes of Gossypium hirsutum L. cotton to get information on genetic variability, heritability and genetic advance as per cent of mean for yield, yield supporting and fibre quality attributes. The value of PCV was higher than GCV which explains that instead of genotypic component, the environmental component also influences in the expression of the character. The characters like number of bolls per plant, number of flower bearing nodes and seed cotton yield recorded higher values of GCV and PCV.

Cotton, Recombinant inbred lines (RIL), phenotypic (PCV) and There is a limited genetic variability available in genetic resources of upland cotton (Gossypium hirsutum L.), which restricted the breeding activity. The objective of present study was evaluating the genetic variability in RIL population derived through intraspecific hybridization between RHAP 12 and RHAP 15 genotypes. The 222 RIL were evaluated during kharif 2018 at University of Agricultural Sciences Dharwad.

Fifty cotton genotypes were investigated for variability and genetic divergence regarding yield related attributes, seed cotton yield and fibre quality traits using principle component analysis. Eleven traits viz., days to flowering, plant height (cm), no of sympodia/plant, no of bolls, boll weight (g/plant), seed cotton yield (kg/ha), Micronnaire value, % Span length, Uniformity ratio, Bundle strength (g/tex) and Elongation ratio were recorded for the germplasm accessions. Maximum variation of about 17.

The working group of G. hirsutum germplasm accessions was characterized for Distinctiveness, Uniformity and Stability testing. Subsequent analysis of data was done to study the genetic diversity available among the accessions using principal component and clustering of 320 cotton germplasm. Under field and laboratory, 26 qualitative traits and 14 quantitative traits were recorded. There is no variation observed for gossypol glands, anther filament colour, male sterility, boll bearing habit and boll opening.
