Technical Abstract: Selection of best families from numerous cross combinations is challenging in sugarcane breeding. The objective of this study is to identify potential families and parents. The experiment was conducted on organic soil at USDA-ARS Canal Point, FL. Seedlings from 8 families were transplanted in a field on May 2021 with identical row spacing (1.5 m) and two intra row spacings of 38 cm (single spacing, SS) and 76 cm (double Spacing, DS) between two adjacent seedlings. A total of 30 seedlings in each family were analyzed. Phenotypic data of juice Brix (%), POL (%), and stalk weight (StWt) were collected from 10 stalks in each replication on mid-December, 2021. The data was used to estimate variance components using mixed model, and to estimate the parental and family effects using restricted maximum likelihood/best linear unbiased prediction (REML/BLUP). Families showed highly significant effect for all traits. When comparing the effect of two different spacing types, DS only significantly increased StWt in some families. Female parent, CP12-1223, had positive and significant (p < 0.05) BLUP estimate for StWt with positive high BLUP values for other two traits followed by CPCL99-2651. Among male parents, CP12-2441 had a high positive BLUP estimates for all traits. Cross combinations of CP17-1934 x CP12-1223 had high BLUP estimate for all traits followed by the cross combinations of CP17-2435 x CP12-2441 and CPCL99-2651 x CP17-1934. This study suggests that families, parents could be selected with high breeding values for multiple traits data. This study will be repeated to confirm this hypothesis.
