Table 2.
Description of grain yield (GY) (ton ha−1), harvest index (HI) (%), spike fertility (SF) (grains/g of chaff weight), and thousand grain weight (TGW) (g) phenotypic traits† evaluated at Citra, FL and Quincy, FL in 2017 and 2018. The best linear unbiased estimates (BLUEs), standard error (SE), heritability (H2), coefficient of variation (CV), maximum and minimum value were calculated for each trait in four environments.
