In addition, maturity indices such as days to flower first initiation (DFFI) and days to first pod maturity (DFPM) were subjected to frequency distribution analysis to elucidate the inheritance pattern in [P.sub.1], [P.sub.2], [F.sub.1], [F.sub.2], and B[C.sub.1] populations in early and medium maturity classes.
Analysis of variance showed highly significant (P < 0.001) differences between the parents and different generations ([F.sub.1], R[F.sub.1], [F.sub.2], R[F.sub.2], B[C.sub.1], RB[C.sub.1], B[C.sub.2], and RB[C.sub.2]) for DFFI, DFF, DFPM, DNDM, H@F, H@M, CW, N_PLT, N_SPOD, H_WT, and G_YD (Table 1).
Phenotypic variances ranged from the minimum of 4.89 average number of days to 69.63 for days to first flower initiation (DFFI) and number of days to first pod maturity (DFPM), respectively.
In the B[C.sub.1] generation, the maturity indices ranged between minimum of 31 days and 45 days and maximum of 46 days and 62 days for DFFI and DNPM, respectively (Figure 1).
The highly significant differences in the maturity traits (DFFI, DFF, DFPM, and DNPM) among the parents and their generations indicated a high level of genetic variation.
In addition, the frequency distribution analysis of the 300 [F.sub.2] plants evaluated also indicated that 229 representing 76.33% fell within early maturity group while 71 representing 23.66% were in medium maturity group for DFFI. Similar observation was made for B[C.sub.1] for the trait.
