Breeding Fibre for the future
Abstract
This paper aims to present the breeder's understanding of fibre and variety characteristics for the next decade. We need to think on that time scale because that is how long it takes us to produce a new variety. In addition, ginning and spinning investments need to consider times of that magnitude to get value from new equipment which may have higher fibre quality targets. What will spinners require? The last two seasons have highlighted shifts in market preference for fibre properties. Base levels for many fibre properties have narrowed, with preference for micronaire between 3.8 and 4.5 (and higher discounts for micronaire above 5.0); fibre length preference is now above 1.125 inches, particularly for some end uses. Fibre strength preference is now above 28 g/tex. These shifts are in addition to the preference for reduced neps, more uniformity in all properties, less trash and no contamination. Our breeding program will utilize these ctiteria in selection at all stages. For segregating material in the early stages of breeding we will exclude lines more aggressively on HVl fibre data. At the end of our breeding timeline, there may be lines ready for release which will be terminated because fibre properties are marginal
