The three growth habit classes of barley are winter, facultative and spring. A winter barley is planted in late fall and is harvested the following summer. A spring barley is planted in the spring and harvested the same summer. If you plant a winter barley in spring, it will not flower, or it will flower too late. If you plant a spring barley in the fall, it will (in many temperate environments) die from low temperature injury. A facultative barley can be planted in the spring or the fall, and it is cold-tolerant. There are three principal physiological traits involved: vernalization sensitivity, photoperiod sensitivity, and low temperature tolerance. Vernalization sensitivity means the plant needs exposure to low temperature before it can flower. Winter barleys are vernalization-sensitive whereas facultative and spring types are not. Photoperiod sensitivity means the plant will not flower until the day length reaches a critical threshold. Many winter barleys, most facultative barleys, and few spring barleys are sensitive to short days. Low temperature tolerance is an induced trait. Winter and facultative barleys are more cold tolerant than spring barleys. Since the traits are controlled by different genes our bets are on photoperiod-sensitive, cold-tolerant facultative varieties. http://barleyworld.org/FAQ_sheet.php Hulled vs. Hull-less The headache of pearls Malt vs. Feed Why some varieties are better for making beer than others •Barley malt is the perfect combination of starch, enzymes, Malt Feed Forage flavors, and aromas for brewing, distilling, baked goods, cereals and confections. There are many types of barley malt – from light to dark – but all are variations on two principal themes: germination and kilning. Different end-uses require different malt quality specifications. Some of the principal characteristics used to define malting quality are protein (low, moderate, or high), malt extract (high), enzyme activity (moderate to high), and beta glucan (low). •Feed barley is used as food for animals. Varieties also differ in their feeding properties but unfortunately feed barley is simply sold by the ton. Feed barley prices are often so low that farmers grow other crops - if they can do so. As a consequence, barley’s adaptability to extreme climates makes it an important feed grain only in areas where it is unprofitable to grow (or import) maize. •Hooded barley is a unique type of feed barley that has hoods, rather than awns. These types are usually cut green for hay or silage. The lack of awns allows for easy chewing by the animals. A rule of thumb is that good malt barley is good feed barley, but not the reverse. In general, malt barley commands a premium over feed barley, but yield less. Many genes determine malting and feed quality; two genes determine the hooded trait. http://barleyworld.org/FAQ_sheet.php Malting barley variety development Grain to Glass 11 – 13 years Time frame (yrs) Activity 2-3 Breeding and selection; initial agronomic assessment •Segregating generations •Doubled haploid populations 3-4 Preliminary to advanced agronomic testing and micro-malting of samples from multiple environments Amount of seed required for Amounts of seed available and scale one malting quality assessment 0 0g – 1 kg for breeding program 200 grams 1 kg – 20 kg for breeding and extension programs 20 kg –100 kg for 3 AMBA Pilot Scale Test must be rated satisfactory in 2/3 years of testing 7 kilograms/ location 2 locations AMBA Plant Scale malting and brewing trials 3 must be rated satisfactory in 3/3 brewing trials 800 metric tons breeding and extension programs.
