JAU-17: A FIRST HIGH YIELDING AND MALTING BARLEY VARIETY SUITABLE FOR MARGINAL LANDS OF PUNJAB.

Wheat Research Institute, Faisalabad, Pakistan developed the ever first variety of barley as Jau-17 in Pakistan. Barley variety performed best in a series of irrigated and rainfed yield trials conducted at Wheat Research Institute, Faisalabad and outstation yield trials throughout the Punjab province during 2008-2019. In the yield trials for three consecutive years from Preliminary to Regular and Advanced Yield Trials, it had out-yielded the check variety Haider-93 by an average of 23.34% while in outstation yield trials throughout the Punjab province, it produced 11.40% higher grain yield than commercial check variety Haider-93. Jau-17 had medium to tall stature of about 99 to 110 cm length, growth habit was semi erect and had medium-length-awned ear which had yellowish white color. It took 90 to 100 days to complete heading and matured in 140 to 145 days with tillering capacity (154-160 per m²). The seed is amber in color with 1000-grain weight of upto 42 gram. For quality trait evaluation it had good quantity for protein (12 to 13.7%) and test weight (52.7 to 58 kg/hl) along with opaque seed surface. Its malt making quality was excellent for industrial uses. In 2019 Jau-17 was approved by Punjab Seed Council for general cultivation due to its superior performance over the years for better grain yield, resistance against rusts and nutrition quality.
