SUMMARY

The present research was conducted to study morphological characters in 40 F1 crosses in oats as per DUS guideline. A total of nine morphological traits on forty oat crosses were observed during Rabi season 2022. All the F1 crosses were grown in randomized complete block design with two replications. The different morphological traits observed are field grown plant viz., plant growth habit, leaf sheath hairiness, leaf blade hairiness, time of panicle emergence, stem hairiness of uppermost node, panicle orientation of branches, ligule shape, plant length (stem) (cm), panicle length (cm). The maximum plant growth was found in erect type for twenty five F1 plant genotypes. The strong leaves sheath hairiness was exhibited high for eighteen F1 plant genotypes. The strong leaf blade hairiness was recorded in eighteen F1 plant genotypes. Medium time of panicle emergence was observed in fourteen F1 plant genotypes. Fifteen F1 plant genotypes were showed for strong hairiness of uppermost node. The erect panicle orientation of branches was found to be in sixteen genotypes. Twenty seven broad edged ligule shapes were observed in F1 plant genotypes. The maximum number of plant length was recorded in fifteen medium F1 plant genotypes. The maximum number of panicle length was observed for medium type of F1 plant genotypes.
