Phenotypic values (mean ± standard deviation) of the parental inbred lines PB260 and PB266, respective F_2:3 families and quantitative genetic parameters for ear fasciation and related traits.

a PB260 and PB266 data obtained from 2010 and 2012 organic production field trial, with 2 replications at Coimbra. F2:3 data obtained from two conventional field trials at Coimbra and Montemor, with two replications. b c—Coimbra and m—Montemor c minF2—top five minimum values of F2 PB260 x PB266; MaxF2—top five maximum values of F2:3 PB260 x PB266. Significant differences exist when no letter repetition occurred between groups d KS—*, **—Significance of the Kolmogorov-Smirnov's test of normality e r—correlation between the two environments per trait. h2—broad sense heritabilities f Significance of the sources of variability: G—Genotype, E—Environment, Rep (E)—Repetitions within Environment, G x E—Genotype x Environment Interaction Levels of significance: ns non-significant value * significant at P < 0.05 ** significant at P < 0.01 *** significant at P < 0.001 Traits measured: yld—yield; cwew—cob/ear weight at harvest; en—ears number; av_ew—20 ears average weight at harvest t; l—ear length; ed 1 to 4—ear diameter 1 to 4; cd1 to 4—cob diameter 1 to 3; kd—kernel dept; m1, m2—medulla 1 and 2; rq1, rq2-rachis 1 and 2; ew-ear weight; cw-cob weight; sw-thousand kernel weight; kw—kernel weight; e_cwew—cob/ear weight per ear; r1, r2—kernel-row number 1 and 2; fa—fasciation; cv—ear convulsion; kn—kernel number; kr—kernel per row. Phenotypic values (mean ± standard deviation) of the parental inbred lines PB260 and PB266, respective F2:3 families and quantitative genetic parameters for ear fasciation and related traits.
