Mustard with high oil content
Among mustard varieties with higher-than-average oil content, one that has gained traction in recent years is ‘Giriraj’, also known as DRMRIJ-31.
Released in 2013-14, Giriraj has been widely adopted in Haryana, Jammu and Kashmir, Punjab, and parts of Rajasthan, Bihar, Madhya Pradesh, and Uttar Pradesh. Its popularity stems from several traits — bold seeds, higher yield (2,225–2,750 kg per hectare), and oil content of 39–42.6 per cent.
Existing mustard varieties, in comparison, yield 1,750–2,400 kg per hectare and have an average oil content of 37–43 per cent.
Giriraj can tolerate cold and heat stress during flowering and grain filling and is resistant to diseases such as Alternaria leaf spot, powdery mildew, and white rust. The oil, with low erucic acid content, is of superior quality and healthier for consumption, while the resulting oilcake serves as an excellent feed for livestock, the ICAR paper noted.
