HI 1628: A high yielding wheat variety for timely sown, restricted irrigation conditions of North Western Plains Zones of India

Abstract

A high yielding bread wheat variety HI 1628 (Pusa Wheat 1628) has been released and notified by the Central Sub-Committee on Crop Standards, Notification and Release of Varieties for Agricultural Crops, Government of India for commercial cultivation under timely sown, restricted irrigated conditions of North Western Plains Zone (NWPZ) of the country. HI 1628 has an average yield of 50.4 q/ha over the zone and showed significant superiority over the checks; with a potential yield of 65.1 q/ha. It has shown an excellent and wider adaptation and significantly superior performance across different irrigation regimes over the checks with an average yield of 45.5 q/ha. It showed high levels of field resistance to stripe and leaf rusts. It is a good quality bread wheat genotype with excellent chapati quality (7.56), bread quality (7.64), biscuit spread factor (8.27) and high sedimentation value (56.6 ml). It has high protein content (~11 %) and protein quality (Glu score of 8/10) for high molecular weight subunits and presence of 5+10 subunit of Glu-D1 reflecting higher gluten strength in the genotype. It has good levels of essential micronutrients like iron and zinc making it rich in nutritional qualities. This variety has promise for timely sown, restricted irrigation planting areas and thus will contribute to increase wheat production and will alleviate the socio-economic status of farmers of NWPZ of India.

Mapping of the QTLs governing grain micronutrients and thousand kernel weight in wheat (Triticum aestivum L.) using high density SNP markers

“…The mapping population consists of 166 recombinant inbred lines (RILs) derived from a cross between HD3086 and HI1500. HD3086 is an Indian high-yielding hexaploid wheat variety suitable for timely sown, irrigated condition developed at IARI, New Delhi (20,21). HI1500 is a popular variety recommended for cultivation under restricted irrigation in central zone harboring many important traits related to drought and heat tolerance (21,22).…”

Assessing the Impact of Mineral Based Nutrient Sources and Nano-Fertilizers on Root Growth, Soil Health, and Nutrient Availability in Wheat Crop

“…The horizontal factors included the sources of phosphorus and potassium as recommended dose of P & K from DAP and MOP (with only SSP in N control plots) @ 60 kg/ ha and 40 kg/ ha, respectively and applied as full dose as basal. The rest two treatments were IMBP + Nano DAP and IMBP + Nano K. IMBP was applied basal @ 1ton/ha and both nano DAP (@5ml/l) and nano K (@300 ppm) were sprayed at maximum tillering stage (40)(41)(42)(43)(44)(45) and booting stage (75-85 DAS). The vertical factors included sources of nitrogen i.e.…”

“…The vertical factors included sources of nitrogen i.e. control with no application of nitrogen; NU @ 3 sprays having three sprays of nano urea @ 5ml/l at Crown Root Initiation (21 DAS), active tillering (40-45 DAS) and 20-25 days after second spray; Basal + NU @ 3 sprays in which basal dose of 50 kg N/ ha was applied through granular urea followed by foliar sprays of nano urea @ 5 ml/l at active tillering (40)(41)(42)(43)(44)(45) and second spray 20-25 days after second spray; RDN having application of 150 kg N/ ha through granular urea in three equal splits as basal, at CRI (21 DAS) and active tillering stage (40)(41)(42)(43)(44)(45).…”

Impact assessment of improved wheat variety disseminated through farmer participatory research in Palwal district of Haryana

“…North West Plains Zone (NWPZ) of India is the largest wheat growing zone of the country and comprises states of Punjab, haryana, Delhi, Rajasthan, uttar Pradesh and uttarakhand (Singh et al 2014). This zone demands improved wheat varieties to suit the irrigated timely sown crop conditions.…”

“…It has shown superior quality parameters with protein content (12.5 percent), a sedimentation value (45 ml), best Glu-1 Score (10/10) and good extraction rate (70.5 percent) meeting all the criteria for superior bread making qualities. This timely shown variety would contribute to increasing wheat production and alleviate the socio-economic poverty of farmers of north-western plains in India (Singh et al 2014). In haryana, wheat is cultivated in 2.56 m. ha with production of 11.55 mt average yield is 45.14 q/ha.…”
