Combining ability study in oat (Avena sativa L.) for physiological, quality traits, forage and grain yield

摘要

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.
