University of Agricultural Sciences, Dharwad

The University of Agricultural Sciences, Dharwad was established on October 1, 1986. The University has 5 Colleges, 27 Research Stations, 6 Agriculture Extension Education Centers, 6 Krishi Vigyan Kendras and ATIC. The University has its jurisdiction over 7 districts namely Bagalkot, Belgaum, Bijapur, Dharwad, Gadag, Haveri, and Uttar Kannada in northern Karnataka. Greater diversity exists in soil types, climate, topography cropping and farming situations. The jurisdiction includes dry-farming to heavy rainfall and irrigated area. Important crops of the region include sorghum, cotton, rice, pulses, chilli, sugarcane, groundnut, sunflower, wheat, safflower etc. The region is also known for many horticultural crops. Considerable progress has been registered in the field of education, research and extension from this University.

    GENETIC INVESTIGATIONS, CHARACTERISATION AND FIBRE COLOUR DEVELOPMENT STUDIES IN NATURALLY COLOURED COTTONS (Gossypium spp.)
    (University of Agricultural Sciences, Dharwad, 1999) SHIRSAT, SIDHARTHKUMAR; KHADI, B M
    Significant genetic variation, moderate to heigh heritability and genetic advance were observed in 22 genotypes and 10 hybrids. Some of the brown linted G. birsutum and G. arboreum genotypes were high performing and could be used directly for commercial cultivation whereas green linted genotypes were poor in performance. No colour cotton genotype was having long, extra long staple length and all genotypes were very poor in fibre strength. The per se performance of colour cotton hybrids was better than their colour linted parents. Some of the colour cotton hybrids were on par with DHH-11 and NHH-44. Similar trend was observed for heterosis. When only colour and white classes were considered it was observed that fibre colour was incompletely dominant and governed by single gene in G. hirsutum and by two-gene interaction (dominant epistasis) in G. arboreum and colour class could be divided into six overlapping classes indicating presence of continuous variation. In colour cotton genotypes significant positive association of seed cotton yield (SCY) and lint yield (LY) was observed with all growth parameters, except for seed index (SI) and boll weight (BW). In hybrids, indirect relation between SCY, LY, LI, GOT and BW and SI made correlations very complex. The fibre fineness was most important fibre quality parameter as it had significant negative relation witli all otlier characters. Its importance was confirmed by path analysis of fibre length. In colour cotton genotypes BW, SI, GOT, LI and in hybrids BW, number of bolls (NB) and GOT were important contributors to seed cotton yield. Lint yield path analysis indicated the importance of SCY, LI, SI in colour cotton genotypes and SCY, LI and BW in hybrids. Path analysis for fibre quality index (FQl) indicated that fibre length, fibre fineness and fibre strength were most important and for counts strength product (CSP) FQl was found most important. Six generation analysis revealed that gene effects like dominance and interaction (DS-28 X DGH-95, DS-28 X DBH95), additive, dominance and additive X dominance (DBH95 X DGH95), additive and interaction (Abadhita X DGH95), additive and dominance X dominance (DBA95 X A-82-1-1) were predominant. The EMS treatments of 0.2 and 0.3 percent were best for G. arboreum and G. hirsutum respectively as they could yield high number of desirable mutants and high variation for yield fibre quality and fibre colour shades. The number of days required for development of colour in fibre varies with genotypes and species. It was 33-37 days after pollination (DAP) in G. hirsutum green, 35-38 DAP in G. hirsutum brown cotton, and 48-51 DAP in G. arboreum brown cotton. It was possible to characterize electrophoretically G. arboreum colour cotton from white ones as it had only one band as compared to three bands in white listed genotypes. In case of G. hirsutum colour and white linted genotypes, characterization was difficult as both had two bands nearly at same Rm distance. The actual pigments responsible for fibre colour in G. hirsutum and G. arboreum were different but pigments belonged to general class of flavonoids.
