Abstract

A new high yielding oat variety OL 15 derived from cross between HJ 8 and OL 1610 was released during the year 2021 for irrigated, timely sown conditions of Punjab. Variety reaches to 50 per cent flowering in 115-120 days and ready for harvesting for green fodder. The variety is low in Acid detergent fiber (ADF) and Neutral detergent fiber (NDF) content but possess high crude protein (CP) content, crude protein yield (CPY) as well as superior nutritional quality for in-vitro dry matter digestibility (IVDMD). OL 15 is semi-erect in stature with high tillering ability, good for single cut system with more desirable morphological plant characters such as plant height, leaf length and leaf width and having medium sized grains. The variety showed high responses to nitrogenous fertilizers and is moderately susceptible to powdery mildew. In the overall performance over five years, mean green forage yield of 852.46 q/ha with a superiority of 23.2 per cent over check (Kent) was recorded. The mean dry matter yield recorded for this variety was 180.1 q/ha with 31.4 per cent superiority over check (Kent). At Faridkot district of Punjab, the variety recorded the highest green forage yield (998 q/ha) which justifies the genetic potential of the variety. The variety outperforms other released and tested varieties Kent, OS 6, and OL 125 in terms of green forage yield, dry matter yield and seed yield. The crude protein yield was 10.80 q/ha with an IVDMD of 50.5 per cent and a CP content of 7.1 per cent. The variety OL 15 was recommended in the year 2021 for cultivation in Punjab state of India.
