MAX FACTS growing tips, news and trivia Alleviating Nut Allergies Disease-resistant Peas The children of women who regularly ate peanuts or tree nuts during pregnancy appear to be at a lower risk for nut allergies than other kids, say researchers. A study published in the Journal of the American Medical Association is the first to demonstrate that a mother who eats nuts during pregnancy may help build up a baby’s tolerance to them after birth, its lead author, Dr. Michael Young, told CNN. The effect seemed to be strongest in women who ate the most peanuts or tree nuts—five or more servings per week. The study controlled for factors such as family history of nut allergies and other dietary practices. (Source: edition.cnn.com) New garden pea and dry pea breeding lines developed by the USDA might offer growers added insurance against Aphanomyces root rot. Fungicides aren’t an option, so growers must either avoid planting in fields with a history of the disease, or switch to growing non-host crops until pathogen numbers drop to acceptable levels. Breeding peas for resistance to Aphanomyces has proven difficult because multiple genes are involved. The resistance genes are also associated with undesirable traits, which cultivated varieties can inherit when crossed with wild germplasm sources. As an alternative, researchers sought to develop pea germplasm lines that naturally tolerate the pathogen, but do not suffer the same ill effects as susceptible plants. The pea lines are descendants of an inbred population of plants derived from a cross made in 1993. (Source: ars.usda.gov) 34 Maximum Yield USA  |  February 2014
