Biometric and phenological indicators data were taken every 15 days that it was evaluated: days to emergence, color of grain, color of the plants before flowering, size of the stem to harvest, size of panicle to harvest, number of leaves to the harvest, days to the milky grain formation, days to the pasty grain formation, days to the physiological maturity and weight of 1000 seeds. Seedbeds were used for germination where 30-day seedlings were obtained, which were later transplanted to the experimental unit. In the biometric indicators, days after germination, it was possible to show that the Mongolian (A. hybridus) species was the earliest with eight days, while the later one was the original species from China with 18 days. In the size of the stem to the harvest, it was possible to show a specific difference of each of the species under study, which varied from 23cm (China) to 130cm (Belgium cruentus). In the panicle size indicator, the behavior had positive correlations with the stem size indicator for some species as in the case of the Chinese species, where the smaller panicle size was evidenced; however, the larger size for this indicator could be observed in the species Belgium caudatus. In the indicator number of leaves to the harvest, it was possible to demonstrate that the species with the lowest biomass accumulated were from China and USA, the one with the highest biomass was the original species of France. In the indicator weight of 1000 seeds it was possible to see a similarity between all the varieties in study data that oscillate between 0.75 and 0.88gr; nevertheless, the species of China was the exception, because its weight reached 0.58gr. From the phenological indicators used in the research, significant results were obtained that can be considered in plant selection processes for the species under study. For the day indicator to the milky grain formation, the variety that presented the shortest time was the species of Argentina (Don Manuel) origin with 118 days, while the one with the longest time was the one from China with 155 days, in relation to the days to the formation of pasty grain, the species that presented the longest time was from China with 170, and the one with the least time was Belgium cruentus with 132 days. The phenological indicator days to the physiological maturity could be observed different dynamics to the one that we had been observing in the other phenological stages so that the lots of days until reaching the physiological maturity was the species from France and China with 193 and 183 days respectively. It is concluded that the original species of Argentina (Don Manuel), France (A. cruentus), Belgium (A.cruentus), Mexico and Belgium (A.caudatus) have potential for Plant Introduction and Selection processes. |
