Study of genetic variations of oat varieties under insufficient and insufficient irrigation

Abstract

A field experiment was carried out in the fields belonging to the Faculty of Agricultural Engineering Sciences /University of Baghdad-Jadriya during the season 2020-2021 in order to study the genetic variations of varieties of oats under lack of irrigation. The experiment was carried out using the design of complete random sectors and the distribution of splintered panels and two factors, the first was the treatment of irrigation at the arrival of humidity ( 50%, 25% and 10%), while the second factor was the varieties (Genzania, Anatolia, plmulao Algoda and healing ) the experiment was carried out three times. The results showed that the third irrigation level exceeded the number of days of planting up to 75% flowering in the second irrigation treatment gave the highest averages for all other qualities studied, and the V4 variety gave the highest average for all qualities except for the weight of 250 grains. . While there was a significant significant difference for the second irrigation level in the values of genetic variation for all accuracy except for the single trait, while we note that accuracy is the number of branches and the total number of branches only and it was highly effective at the first irrigation level. Later, the effect was good at the second irrigation level. The difference is in appearance. It is noted that the values at the second level of road types, except for the obtained characteristic and the nature ratio, gave the second level of irrigation the highest average for most types of resistance. Why is it not different from what was mentioned above, which did not adopt a study of scientific variations in the expected researchers, as you would expect, the second irrigation and the V4 variety, which recorded the highest averages for the characteristics that were studied.
