Evaluation of Northern-Grown Crops as Hosts of Soybean Cyst Nematode

Abstract

Sixty-two cultivars/varieties of thirteen crops grown in the northern Great Plains were evaluated for suitability as hosts of the soybean cyst nematode (SCN; Heterodera glycines Ichinohe) (HG type 0) using soybean Lee 74 as the susceptible host. “Cone-tainers” with autoclaved sand were infested with 2,000 eggs placed into a 2-cm × 1-cm hole and then a 3-day-old germinated seed was placed in the hole. “Cone-tainers” were placed in sand in plastic pots immersed in a water bath at 27°C in the greenhouse. Plants were harvested after 30 days, and females were extracted and counted. A female index (FI = the average number of females on the test plant divided by the average number of females on soybean Lee 74 times 100) was calculated for each cultivar to assess host suitability to the nematode. FI's ≥ 10 indicated a suitable host. Canola, clover, lentil, and sunflower were nonhosts (no evidence of reproduction), while borage, camelina, chickpea, crambe, cuphea, field pea, nyjer, and safflower were poor hosts for SCN with FI's less than 8. Lupines were the only suitable host with FI's of 42 to 57. This is the first report of reproduction of SCN on chickpea, crambe, cuphea, and nyjer. Accepted for publication 2 December 2009.

Population dynamics of the nematodes Heterodera glycines and Pratylenchus brachyurus in a succession crop of soybean and chickpea

“…For race 3, the highest level of reproduction occurred in red dead-nettle, field pennycress, and common henbit (Venkatesh et al, 2000). Poromarto and Nelson (2010) found that the chickpea was not an efficient host of H. glycines race 3, although it allowed the multiplication of a small number of this nematode. However, Cardoso et al (2019), who evaluated the resistance of rattlepod (Crotalaria ochroleuca) to races 1, 2, 3, 5, 6, and 14 of H. glycines, found that this plant species was resistant to races 1, 2, and 5 but was susceptible to race 3 and showed varied reactions to races 6 and 14.…”

“…Heterodera glycines can also colonize other plants like sunn hemp (Crotalaria juncea), pigeon pea (Cajanus cajan) (Valle et al, 1996), common bean (Phaseolus vulgaris), azuki bean (Vigna angularis), and mung bean (Vigna radiata) (Rossi & Ferraz, 2001). Poromarto and Nelson (2010) verified that chickpea was a poor host of H. glycines race 3; however, there are no studies on H. glycines race 5. Cardoso et al (2019) evaluated the resistance of Crotalaria ochroleuca to races 1, 2, 3, 5, 6, and 14 of H. glycines, and verified that it was resistant to races 1, 2 and 5, but was susceptible to race 3 and showed varied reactions to races 6 and 14.…”

The role of Crambe abyssinica in the control of Heterodera glycines (Thylenchida: Heteroidae)

“…This result confirms the resistance of variety D (P98Y51), which linearly decreased the female population for 90 days. Poromarto and Nelson (2010) evaluated the invasion potential of H. glycines in several plant crops and found that SCN populations did not grow in C. maritima. This result corroborates the findings of the present study by inferring that Crambe sp.…”

Pectate lyase is a factor in the adaptability for Heterodera glycines infecting tobacco

“…The SCN is known to attack a wide range of plants including Fabaceae and non-fabaceous hosts like Carthamus tinctorius, Camelina microcarpa, Borago officinalis and Cuphea viscosissima, etc. (Noel 1993;Poromarto and Nelson 2010). In the Shandong and Henan provinces of China, Cheng et al (2012) and Shi and Zheng (2013) reported that the tobacco is also parasitized by SCN, however, the mechanism of this interaction is not known.…”
