Anabel a new cotton variety

Valentina Dimitrova

Abstract: The aim of this research was to study the productive potential and to evaluate the technological fiber properties of the new cotton variety Anabel, compared to the standard varieties. The new variety was studied in competitive varietal trials conducted in 2014-2017 in the experimental field of the Field Crops Institute in Chirpan. In the IASAS system, the Anabel variety was tested in 2017-2018. It was approved for the new cotton variety in 2021. Anabel variety was obtained by intraspecific hybridization and belongs to the species Gossypium hirsutum L. Anabel is an early and productive variety. According to IASAS, in seed cotton yield - 2026 kg/ha, on average for two years, it was inferior by 3.1% to the cultivar Chirpan-539 - standard for productivity and was equal to the cultivar Avangard-264 - standard for fiber quality. In terms of fiber yield, it was equal to Chirpan-539 and was superior to Avangard-264, as a result of the higher lint percentage. This new variety showed a number of valuable fiber technological qualities and in some respects exceeded both standard cultivars or was equal to Avangard-264. Compared to the standard cultivars, the variety Annabel had a better fiber spinning (SCI) Index, longer fiber, lower micriner, greater strength and better spectroscopy with reflection of the RD difference. The obtained results define the new variety Anabel as a very good combination of earliness, productivity and fiber quality. This makes it very valuable for cotton production and selection programs with cotton.
