Phenology
The difference in panicle emergence time ranged between 53 to 64 DAS the white commercial cultivar being the earliest to enter the reproductive stage at 53 DAS (Table 6), along with 53-1-B. In general, the brown lines exhibited earlier heading compared to their white-counterparts. 53-3-W was the latest to head and had the highest DSP, DPM and DSM within the collection. While the white commercial cultivar was significantly earlier than brown 44A-163-B, their grain filling period (indicated by DPM) was not statistically different. Both the pure brown 44A-163-B and the white cultivar exhibited the lowest DSM in the collection.
