Abstract
Cotton is immensely important fibre crop of India having great role in economy. The quality seed is foundation for achieving desired production targets. Therefore, an experiment was conducted to assess the seed vigour traits in cotton (Gossypium hirsutum L.) and its association with seed cotton yield to predict the seed potential at Department of Agricultural Botany, Dr. Panjabrao Deshmukh Krishi Vidyapeeth Akola, Maharashtra (India) during the 20182019 with seven genotypes of G. hirsutum cotton viz., AKH-13-55, AKH-13-81, AKH-14-59, AKH-14-12, AKH-13-92, AKH-13-26 and AKH-13-51. The analysis of six vigour traits in laboratory along with fifteen yield and yield contributing traits in field with objectives to estimate the mean performance of seed vigour traits in cotton and to assess the correlation between seed vigour traits and yield contributing characters. Genotypes viz., AKH-14-12 and AKH-13-26 exhibited superiority for all six vigour traits, as well as found top ranking for most of yield contributing traits. Correlation coefficient analysis revealed that all six seed vigour parameters were significantly correlated with all fifteen yield and its contributing traits in positive direction except ginning outturn and oil content which exhibited non significant association. The positive and highly significant correlation were recorded in between seed cotton yield per plant and all six vigour traits viz., germination per cent (r0.623), root length (r0.871), shoot length (r0.516), seedling dry weight (r0.754), seed vigour index-I (r0.905) and seed vigour index-II (r0.757). Hence, utilization of seed vigour traits is possible and effective for the prediction of yield potential in cotton along with planting value of seed lot.
