Description |
Fifty genotypes of barley (Hordeum vulgare L.) were assessed to study the performance and variability based on seed quality traits during rabi 2016-17 at CCS Haryana Agricultural University, Hisar. The observations were recorded for eight seed quality traits viz., seedling length (cm), seed density (g/cc), germination (%), seedling dry weight (mg), vigour index I, vigour index II, electrical conductivity (µS/cm/seed) and accelerated ageing at 48 and 72 hours. Genotypes significantly differed for all the traits under study indicated existence of sufficient variability in the experimental material under both environments. Nine genotypes viz., 2nd GSBSN-28 (2015), IBYT-HI-17, UPB 1059, BH 15-17, 2nd GSBSN-15-8, BH 14-25, 2nd GSBSN-60 (2015), DWRB 143 and IBYT-HI-20 werefound significantly superior for one or more traits among 50 genotypes under timely sown while, six genotypes namely, BH 14-42, RD 2909, AZAD, 2nd GSBSN-28 (2015), IBYT-HI-18 and IBYT-HI-16 were exhibited significant superior performance under late sown environment. The estimates of phenotypic coefficients of variation (PCV) and genotypic coefficients of variation (GCV) indicated that PCV was found greater than GCV for all the characters in both timely as well as under late sown conditions. Among all the traits, seed density had highest phenotypic and genotypic coefficient of variation under timely whereas, under late sown, accelerated ageing (72 h) showed maximum PCV and GCV. Germination (%) exhibited minimum PCV and GCV under both the environments. Moderate to high heritability coupled with high genetic advance under timely sown was observed for seedling density, accelerated ageing (72, 48 h) and electrical conductivity likewise, for accelerated ageing (72 h), seedling dry weight and vigour index I under late sown indicating the importance of these seed vigour traits in crop improvement.
