Oat Floral Biology and Factors Affecting Seed Set

Abstract

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.

Hybridization and Factors Influencing Seed Set in Oat

“…Pollen seems to be at its best just before natural anthesis. (Hilli and Kapoor, 2021). On some days, suitable pollen is only available for an hour, but on others, it is available for many days.…”

Principal Component Analysis in advanced breeding lines of oat (A. sativa × A. sterilis)

“…In India, about 5.0 lakh ha is under oat cultivation. In rabi, the crop is raised mainly for fodder in north western and central parts of the country and the crop is now even expanding in the eastern regions of the country as well (Hilli and Kapoor, 2021). It is the seventh most economically significant cereal crop following corn, rice, wheat, barley, sorghum and millets.…”
