Interpretive Summary: Ginning and spinning tests were run to evaluate a small seeded variety (DP555) in comparison to a more standard variety (DP451). There were some significant differences in ginned fiber quality and seed loss between the varieties with DP451 being somewhat superior. However, the DP555 fiber made yarn as good as or better than the yarn made from DP451. These tests did not show any significant problem in spinning DP555 in relation to seed size.

Technical Abstract: A laboratory ginning test was conducted to compare the ginning performance, fiber quality, and spinning properties of a newly developed small-seeded variety (DP 555 BG/RR) against a larger-seeded standard commercial variety (DP 451 B/RR). Ginning tests concentrated on 1) evaluating seed loss and seedcoat fragment generation during ginning and any effects on spinning performance, and 2) evaluating an experimental ginning rib's effect on seed loss and seedcoat fragment generation. Fiber and spinning tests indicated that, even though DP 451 was somewhat longer, had fewer neps, and had lower seed loss rates, DP 555 made yarn whose properties were as good as or better than that made from DP 451. Evaluation of the expermental rib indicated that it had positive results on fiber and yarn properties for DP 451 but negative results on those same properties for DP 555. These data indicate that further tests need to be conducted to better understand the interaction of seed size and gin stand design, particularly on very small-seeded varieties.
