Abstract:
Eighteen hybrid combinations developed by crossing three lines and six testers in Line X Tester mating design were evaluated along with their parents including three checks with two replications in Randomised Block Design for seed cotton yield, yield contributing and fibre quality traits in desi cotton during kharif, 2021 at Cotton Research Station, Mahboob Baugh, VNMKV, Parbhani. Heterosis was estimated in relation to better parent (Heterobeltiosis) and standard checks (Standard heterosis). The magnitude of heterosis, heterobeltiosis and standard heterosis for all the characters in the current study was highly appreciable. Among eighteen crosses, the crosses showed the highest and desirable significant standard heterosis for various traits viz., cross PA 833 x JLA 505 for days to 50 per cent flowering; PA 904 x CNA 1032 for plant height, boll weight and ginning percentage; PA 899 x PA 740 for number of sympodial per plant; PA 833 x CNA 1032 for number of bolls per plant, seed cotton yield per plant, seed index and lint index; PA 904 x PA 785 for upper half mean length and fibre strength; PA 833 X AKA 7 for fibre fineness; PA 904 x AKA 7 for uniformity ratio over standard check PKVDH 1,PKV Suvarna and NACH 12, respectively. The crosses PA 899 x CNA 1032, PA 833 x CNA 1032 and PA 833 X AKA 7 for seed cotton yield and yield contributing traits, while crosses PA 904 x PA 785 and PA 833 X JLA 794 for fibre quality traits hold promise for further evaluation and commercial exploitation of heterosis.
