In India, oat is grown as fodder crop during Rabi season in north-western and central parts of the country and is now even extending to eastern region as well. The only commercially cultivated species in the genus Avena are Avena sativa, Avena nuda and Avena byzantine. Oat flowers are bit delicate when compared to other cereal floral structure and seed set is influenced by many factors during artificial hybridisation. This paper includes about floral biology of oat crop and also the various factors responsible for seed set during hybridisation viz effect of Interval Between Emasculation and Pollination, effect of temperature for seed set and any Injury to floral Parts during hybridisation.

“…On hot days usually simply opening and closing florets to extract one anther resulted in a 30 to 50% reduction in seed set, but only a 5 to 10% reduction on cool days. Clipping the spikelets partially exposed the primary floret pistils, which decreased seed set significantly on hot days but not so much on cool days (Brown and Shands, 1956).…”

Background: Oat is mostly neglected crop for hybrid development due to its floral structure which results in high damage rate during hybridisation. Due to the cumbersome in acquiring a sufficient number of hybrids and subsequent backcrosses are difficult that lead to lack of much inheritance studies in Oats. Methods: The procedure for crossing used was almost identical to that used by oat breeders which was conducted for 2 years viz., 2019-20 and 2020-21 at Forage Station, Punjab Agriculrural University, Ludhiana. Result: The experiment was conducted to know the seed set percent in oat cultivars. Since the oat flower is fragile compared other cereals and it is easily harmed during the emasculation and pollination process. The seed set percent observed was only 12 and 10 percent in the year 2019-20 and 2020-21, respectively.
