RH-749 in detail
RH-749 is a hybrid mustard from Haryana Agricultural University (HAU), Hisar, with a strong record of yield gains across northern India, including frontline demonstrations in Jammu & Kashmir and irrigated parts of Rajasthan.
Origin & story
Developed at Haryana Agricultural University (HAU), Hisar in 2013. It became a benchmark in HAU's mustard breeding: when the university released RH-1975 about a decade later, it was positioned as giving roughly 12% more yield than RH-749, which shows how widely RH-749 had been adopted as the variety to beat.
How it grows
Listed at 146-148 days to harvest and suited to north India's rabi conditions — recommended for Haryana, Punjab, Delhi, Jammu and north Rajasthan. It responds well to fertility management: in a trial under tarai conditions of Uttarakhand, 120 kg/ha nitrogen with 40 kg/ha phosphorus gave 2,135 kg/ha seed yield and 793 kg/ha oil yield. It has also featured prominently in cluster frontline demonstrations in Rajasthan, where mustard CFLDs averaged about 22% yield gains over farmer practice.
Quality & character
Hybrid vigour type. In the Uttarakhand fertility trial at the higher nitrogen rate it carried about 327 siliquae per plant, 15.4 seeds per siliqua, 4.3 cm siliqua length and a 1000-seed weight of 4.3 g, with oil content around 40%. It performed better than RH-725 on yield and water-use efficiency under varying irrigation, and the PM-22 × RH-749 cross showed 16.28% better-parent heterosis for seed yield in breeding trials.
Why it matters to buyers
Frontline demonstrations have shown sizeable advantages over farmer practice — the baseline records a 62.6% gain in Jammu & Kashmir and 29-40% gains in Rajasthan demonstrations, and a Hanumangarh (Rajasthan) demonstration recorded 1,450 kg/ha against a local check of 1,220 kg/ha (about 19% higher). At roughly 40% oil with up to 793 kg/ha oil yield under good fertility, it interests oil millers. Best suited to irrigated and assured-rainfall zones where nitrogen and phosphorus can be managed, and pairs well with extension advice on timely sowing and balanced fertiliser.
About mustard
Indian mustard (Brassica juncea) occupies over 90% of India's rapeseed-mustard acreage and has evolved through systematic breeding since the 1960s paired with farmer landraces across the rabi belt from Punjab to Madhya Pradesh. Below are 12 foundational varieties—both landmark releases from ICAR institutes and notable hybrids—that define Indian mustard…
