Abstract
JAU-17: A first high yielding malting barley variety suitable for marginal lands of Punjab ABSTRACT For the usage of beverages and malting purpose, Wheat Research Institute, Faisalabad, developed the ever first variety of barley crop with the name Jau-17 in Pakistan. It is a two rowed 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 yield trials for three consecutive years from Preliminary to Regular and advanced Yield Trials, it has out-yielded the Check Variety Haider-93 by an average of 23.37% while in Outstation Yield Trials throughout the Punjab province, it produced 11.5% higher grain yield than commercial Check variety Haider-93. Jau-17 has medium to tall stature of about 99 to 110 cm length, growth habit is semi erect and has medium-length-awned ear which has yellowish white color. It takes 90 to 100 days to complete heading and matures in 140 to 145 days. It bears good tillering capacity (154-160 per m). The seed is amber in color with 1000-grain weight of upto 42 gram. For quality trait evaluation it has good quantity for protein (12.2 to 13.7%) and test weight (52.7 to 54.4 kg/hl) along with opaque seed surface. Its malt making quality is excellent for industrial uses. In 2019 Jau-17 was approved by Punjab Seed Council for general cultivation due to its stable performance over the years for better grain yield, resistance against rusts and nutritional quality. Key words: Jau-17, barley, moisture stress tolerance, beverage industry, irrigated, 2-rowed barley, malting, grain yield.
