Observations of Promising Lines in Oat (Avena sativa L.) at Samoeng Rice Research Center, Samoeng, Chiang Mai สิปปวิชญ์ ปัญญาตุ้ย

Abstract

The objective of this study was to evaluate agronomic characteristics of oat-promising lines collected at Samoeng Rice Research Center, Samoeng district, Chiang Mai during the growing season of 2021/2022 – 2022/2023. The results of the 100 promising lines in 2021/2022 found that only 20 lines of SMGOTC21099, SMGOTC21100, SMGOTC21074, SMGOTC21042, SMGOTC21089, SMGOTC21094, SMGOTC21060, SMGOTC21090, SMGOTC21086, SMGOTC21081, SMGOTC21058, SMGOTC21045, SMGOTC21080, SMGOTC21079, SMGOTC21092, SMGOTC21062, SMGOTC21095, SMGOTC21061, SMGOTC21053 and SMGOTC21001 showed reasonable yield ranging from 104.73 to 177.85 g/1.2 m².  Therefore, these 20 lines were selected to grow in 2022/2023 with the randomized complete block design (RCBD) experiment of 3 replications. The results showed the highest yield per area ranged from 837.46 to 921.97 g/2.4 m² while SMGOTC21099 had a higher of 1,000-grain weight and yield per area than the control lines for 22 and 8 % respectively. This line could be selected for further yield trials for a certified oat variety.
