Quantitative Gene Action for Protein Content in Oats
1975
Sraon, H. S. | Reeves, D. L. | Rumbaugh, M. D.
The objectives of this study were to determine gene action, heritability, and number of effective factors controlling protein content in oats (Avena spp.). One Avena sterilis L. and three A. sativa L. cultivars were crossed in a diallel, including reciprocals, with protein of 16.1 to 24.4%. The data showed additive gene action for groat protein percentage. Partial dominance for low protein percentage was observed. Narrow sense heritability was 41%. Protein percentage was inversely related to grain yield. The Avena sterilis L. parent exhibited recessiveness for high protein content. Estimation of the number of effective factors controlling protein content varied from 1 to 25 depending upon the genetic diversity of the parents and direction of the cross.
