Future cotton production systems need improved fiber quality to meet global market demands and provide the textile industry with high-quality fiber. To achieve this, cotton (Gossypium hirsutum L.) breeding programs must develop cultivars that overcome the negative relationship between agronomic performance and fiber quality. Since 1935, the USDA-ARS Pee Dee germplasm enhancement program has prioritized improving fiber quality while also maintaining or enhancing agronomic performance. Along with a number of other breeding programs, the Pee Dee program documented that the negative relationship between agronomic performance and fiber quality is most often caused by genetic linkage. Several of these breeding programs have demonstrated that the negative genetic linkage can be overcome. In this study, we test the hypothesis that three Pee Dee germplasm lines previously identified as rare recombinants can generate populations with a decreased negative relationship between agronomic performance and fiber quality. The results suggest that two of the three Pee Dee germplasm lines generate populations with a decreased negative relationship and presumably transmit beneficial allelic combinations for lint percent and fiber quality traits in coupling phase linkage with one another or fixed in offspring.

“…The quality of cotton is determined by its fibre length, strength, micronaire, uniformity, and elongation. The length determines the spinning efficiency as lengthier fibre produces long yarns (Koebernick et al ., 2019). Strength is necessary to maintain cotton's natural qualities after fabric processing.…”

Cotton is one of the most important crops among natural fibres. Fibre quality determines the spinning ability, which is negatively correlated with yield and yield-contributing traits. Limited efforts have been made to improve fibre quality and yield in diploid cotton. Therefore, screening a large panel of germplasm lines can help identify genotypes with better fibre quality and yield. We evaluated 712 desi cotton genotypes for fibre quality traits. The genotypes showed a significant difference for all the traits, suggesting considerable variability for fibre quality improvement. Fibre length and strength showed high phenotypic and genotypic coefficients of variation. Heritability was high for fibre strength, length, and elongation. Fibre length and strength were positively correlated; however, micronaire was negatively correlated with these two traits. Superior accessions were identified for fibre length (11), strength (20), uniformity (7), and elongation (25) among genotypes. Most of the desi lines (71%) had medium micronaire values. Twenty accessions identified were ideal for spinning, showing the fibre strength-to-length ratio of one. Cluster analysis based on Euclidean distance grouped all 712 accessions into four major clusters. Principal component analysis biplot revealed that accessions AC3418, 360-SP1, AC3522B, Kanpur A, Gao16CB-9, and AC3370 were genetically diverse. The superior accessions for fibre quality identified in this study are potential lines for the diploid cotton improvement programme.
