Agronomic evaluation of regenerant oat (Avena sativa L.) lines

Boryana Dyulgerova, Todorka Savova

Abstract: Mature embryo-derived somaclones regenerated from variety Kehlibar and breeding line 471-3 were analyzed for agronomic traits to evaluate the potential of tissue cultures to induce genetic variability in agronomic traits in oat (Avena sativa L.). The selected lines and their parents were evaluated in the experimental field of the Institute of Agriculture – Karnobat, Southeastern Bulgaria, during 2013/2014 and 2014/2015 growing seasons. Traits: plant height (cm), panicle length (cm), number of spikelets per panicle, number of grains per panicle, grain weight per panicle (g), 1000 grain weight (g), protein content, crude fat content and grain yield were studied. The results indicate significant differences among the regenerant lines and their parents in yield and yield related traits. Regenerant lines with lower plant height, longer panicle, higher number of spikelets and grains per panicle, higher grain yield and higher 1000 grain weight and higher protein and crude fat content compared to parents were founded.
