Abstract

The experimental material comprised of ten oats (Avena sativa L.) genotypes and their 45 F1 crosses evaluated for physiological parameters, forage quality, green fodder yield plant-1 (g) and grain yield plant-1(g). The highest crude protein content was recorded in SKO-208. The lowest Neutral detergent fiber (NDF) was observed in SKO-213. Lowest Acid detergent fiber (ADF) was observed in SKO-204. Lowest crude fiber was observed in SKO-213. Highest ash content was observed in SKO-209. The highest chlorophyll content was recorded in SKO-211. The highest leaf area index (LAI) was recorded in SKO-211. The cross combination SKO-212 × SKO-213 recorded for the highest crude protein content. The cross combination SKO-205 x SKO-207 had lower range of NDF. The lowest range of ADF was observed in cross combination SKO-204 × SKO-211. The cross combination SKO-207 × SKO-212 recorded the lowest crude fibre. For ash content SKO-205 × SKO-212 were found to be superior. The highest chlorophyll content was recorded in genotypes SKO-211 and SKO-208. The cross combination SKO-211 × SKO-212 recorded the highest chlorophyll content. The highest LAI was recorded in genotypes SKO-211 and SKO-208. The highest LAI of cross combination SKO-207 × SKO-211 were found to be superior. The highest forage yield and grain yield observed in SKO-205 and SKO-SKO-208. The cross combinations SKO-211 × SKO-212 and SKO-207 × SKO-211 were found to be superior for forage and grain yield.

Key words: Avena sativa L., quality parameters, acid detergent fiber (ADF), neutral detergent fiber (NDF).
