Interpretive Summary:

Technical Abstract: Not much information is available in the literature on the effect of seed size on ginning efficiency in upland cotton. In 2015 and 2016 nine diverse upland cotton cultivars and germplasm lines were planted at two locations in Stoneville, MS to test the above relationship. Two of the cultivars (Ark 9317-26 and DP 555 BG/RR were classified as ‘small’ because they have seed index (SI) of < 10 g. FM 832, FM 966, and MD 15, had SI ranging from 10-12 g and were classified as having ‘intermediate’ seed size. TAM 182-34 ELS and three other breeding lines from Stoneville, MS (201-2, 107-1, and 152-1) had ‘large’ seeds with SI of > 12 g. The materials were planted in three replications each at two sites in both years at Stoneville. Data were collected on ginning energy requirement (Wh kg-1 lint), ginning rate (g lint s-1), fibers per seed, seed surface area, fuzz percent, gin turnout, HVI and AFIS quality parameters. The objectives of the test were to see the effects and interactions of seed size with the above parameters. Statistical analyses of all properties associated with the genotypes were performed using Proc ANOVA. Simple Pearson’s correlation tests and regression analyses were conducted to test the relationship between traits. Small and intermediate seeded genotypes had significantly higher ginning rate than large seeded genotypes. However, larger seeded genotypes required significantly higher ginning energy. Seed size was positively and significantly correlated with net ginning energy, seed index, fuzz %, and seed surface area but negatively and significantly correlated with lint turnout and fiber uniformity. Relationships with ginning rate and fibers per seed were negative but not statistically significant.
