Breaking the Yield-Fiber Quality Barrier
|
ABSTRACT Lint yield and fiber quality were evaluated on all new conventional strains developed from 1995 to 2000. Few strong associations were detected for lint yield versus fiber length, strength or micronaire. Positive and consistent correlation existed for lint yield and lint percent, as well as, lint percent and micronaire. For each years new strains, the top five high yielding (HY) lines were compared with the top five high yielding plus improved fiber quality (IQ). The HY lines generally yielded higher than the IQ lines. However, several lines were identified that had both high yield and high fiber quality. The introduction of diverse genetic backgrounds as parents appears to have contributed to the more recent increases in both lint yield and fiber quality. Within these germplasm pools, success in breeding for both high yield and improved quality is certainly attainable when both fiber and yield selection criteria are utilized. |
