The Genetic Parameters Of Several Oats Cultivars Under The Influence Of The Biofertilizer (Humiforte) Spraying

Abstract

A field experiment was conducted in the fields of the college of Agriculture - University of Anbar (alternative location) during winter seasons in 2015-2016 and 2016-2017. To study the effect of spraying with four concentrations of Humiforte 0, 2, 4 and 6 L.ha−1 on growth and yield of four Oats cultivars. The layout of the experiment was split plot design according to RCBD design with three replicates. The results showed the following: The characters of the yield and yield components of oats were studied in terms of performance and variability and calculated the values of genetic and environmental variability and the heterogeneity, phenotypic and inheritance. The highest percentage of genetic variations to the environment 7.2, 10.9 and 13, 7 for the flag leaf area and the number of grains by the raceme in both seasons. the highest percentage of heritability was found in flag leaf area reached 87.8%, 91.60 and the number of grains by the raceme which reached 92.72% and 87.36% in both seasons. The concentration of 6 L.ha−1 was superior compared to the other concentrations in plant height, leaf area, number of branches per plant, leaf content of chlorophyll, yield components and grain yield 6.01 and 6.29 ton.ha−1 in both seasons respectively. Genzaniya and Hamel cultivars gave the lowest number of days to reach the flowering stage, while Gensaniya cultivar gave the highest plant height, leaf area, chlorophyll leaf content, number of grains by raceme and grain yield 5.47 and 6.48 ton.ha−1 in both seasons respectively. However, Shefaa was superior in the weight of 500 grains in both seasons. The interaction between the study factors was significant in most of the studied characters. The treatment of Gensaniya at the concentration of 6 L.ha−1 gave the highest grain yield reached 6.86 and 7.22 ton.ha−1 in both seasons respectively. We conclude from this results that most components of the crop are more influenced by genetics factors. Therefore, we recommend the adoption of the number of grains per raceme in the assessment of productive capacity of the oats grains.
