TAILIEUCHUNG - Heterosis for productivity and fibre quality traits among hybrids derived from diverse lines of Gossypium hirsutum L.

A study on heterosis for seed cotton yield and fibre quality traits was carried out at Agricultural Research Station, Dharwad farm during kharif 2017. The material comprised of 28 intraspecific hybrids, their parents and standard check DHH-11 which were evaluated in randomized complete block design (RCBD) with two replications. The analysis of variance indicated the presence of substantial variability among the experimental materials for yield and fibre quality traits. The hybrid KDHH-22 exhibited significant positive heterosis over the standard check for seed cotton yield per plant and ginning outturn. The hybrid KDHH-4 recorded high significant standard heterosis for number of sympodia per plant and uniformity ratio, as well as high mean performance for plant height and lint index. The other hybrid, KDHH-11 exhibited significant standard heterosis for seed index and fibre strength. The hybrids KDHH-9, KDHH-24, KDHH-19, KDHH-27 exhibited high significant the standard heterosis for number of monopodia per plant, number of bolls per plant, boll weight and micronaire value respectively in desirable direction. The cross KDHH-13 recorded significant heterosis over standard check for UHML and elongation. The hybrids KDHH-22, KDHH-1, KDHH-8, KDHH-7 and KDHH-6 were identified as best hybrids for seed cotton yield and fibre quality traits which can be exploited through heterosis breeding. | Heterosis for productivity and fibre quality traits among hybrids derived from diverse lines of Gossypium hirsutum L.
