Abstract The present investigation was conducted in the Plant Production Department, Faculty of Agriculture (Saba Basha), Alexandria University to clarify the relationship between the classer’s grade (CG) and both 3-digit color (3-DCG) and the trash grades obtained from the High-Volume Instrument (H.V.I.). Besides, the contribution percentage of the HVI fiber properties to the classer and instrumental grades should be calculated and used to predict those grades. Five commercial Egyptian cotton varieties namely: Giza 87 and Giza 92 (belong to extra-long staple), Giza 94, Giza 86 and Giza 90 (belong to long staple) were involved in this study through 2017 and 2018 seasons. Data of the Classer Grade and its corresponding H.V.I. fiber properties of the different grades belonged to the five cotton varieties were attained from the Cotton Arbitration and Testing General Organization (CATGO) laboratories at Smouha and the Modern Nile Company, Alexandria, Egypt. Complementry data of six grades [Good/Fully Good (G/FG), Good+3/8, Good+5/16, Good+1/4, Good+1/8, Good), in four replicates, of the two seasons 2017 and 2018, were collected for each cotton variety. |
