1 VARIETY GUIDE P eanut varieties of today have resistance to multiple diseases, but the best variety choice is still one that will achieve a rapid, uniform stand and provide good yields and grades over a wide range of growing conditions. With so many varieties to choose from, careful consideration should go into this part of your planting decision. Many factors affect the decision of what variety to plant including field history, irrigation, 12 / THE PE ANUT GROWER FEBRUARY planting and harvest capabilities, seed availability and quality and marketing. On a field-byfield basis, weigh all of these factors to determine how the variety may fit into your situation and on your farming operation. Study the variety descriptions and the trial data. If you are thinking of planting a new variety, follow up by asking questions of researchers and other growers about their experiences with those varieties. PG PE ANUTGROWER.COM

5 2018 VARIETY GUIDE released by the program. It is medium maturing at approximately 140 days. It has moderate resistance to Sclerontinia blight and should be suited for production in all areas of the Southwest. Seed size is considered medium. VIRGINIA-TYPE VARIETIES Emery: Emery is a release by the North Carolina State University named in honor of Dr. Donald A. Emery, peanut breeder at NCSU. Emery is a high oleic large-seeded Virginia-type cultivar with alternate branching pattern, intermediate runner growth habit and medium green foliage. Emery has approximately 67 percent jumbo and 24 percent fancy pods, and seeds with tan seed coat averaging 940 mg seed-1 (480 seed lb-1). It also has 18 percent super-extra-large kernel content, 44 percent extra-large kernel content, and 71 percent sound mature kernel content. Emery is partially resistant to three of four major regional diseases: leaf spot, Sclerotinia blight, and Tomato Spotted Wilt virus, but it should be considered susceptible to Cylindrocladium black rot. Emery has bright pods and flavor comparable with run16 / THE PE ANUT GROWER FEBRUARY ner-type standards. s and the number of days to maturity are similar with Bailey (145 days). Sullivan: Sullivan is a 2013 release by the North Carolina State University. Sullivan is a high oleic Virginia-type cultivar with alternate branching pattern, intermediate runner growth habit and medium green foliage. It was developed from a cross with a sister line of Bailey and it has partial resistance to early leaf spot, CBR, Sclerotinia blight and TSWV. Sullivan has approximately 45 percent jumbo pods and 40 percent fancy pods, and seeds tan with seed coat averaging 931 mg seed-1. s and the number of days to maturity are similar with Bailey (145 days). Wynne: Wynne was released by the North Carolina State University in Plants resemble Sullivan, with which Wynne is related through a Bailey sister line. Wynne has partial resistance to early leaf spot, CBR, Sclerotinia blight and TSWV and has the high oleic characteristic. The percentage of jumbo pods is 68 and fancy pods 21 for this cultivar. Seeds have pink seed coat and seeds average 1051 mg seed-1. Just like Sullivan, Wynne has yields and maturity similar with Bailey, but significantly higher than CHAMPS, Gregory, PE ANUTGROWER.COM

6 NC-V11, Perry, and Phillips. Bailey: Bailey, released in 2008 by NCSU, is a medium to large-seeded and high yielding Virginia-type peanut. It produces high yields across multiple years and locations, which is an indication of good tolerance to fluctuations of weather and growth conditions. Bailey has a growth habit intermediate between runner and bunch types, bright pods and tan kernel color. More importantly, it is resistant to TSWV and thrips. It matures in approximately 145 DAP, just a little after CHAMPS, but it holds pods much better than CHAMPS if picked later. Sugg: Sugg is a line developed at the NCSU that has resistance to TSWV, CBR, SB, and early leaf spot. Sugg has an intermediate runner growth habit and the color of seed coat is pink. Sugg produces high yields and has larger kernels than Bailey. It also has good blanching and flavor characteristics. Titan: Titan, released in 2010 by Virginia Tech, is an extra-large seeded peanut with an exceptionally high content of jumbo pods and super extralarge kernels. It is suitable for in-shell, gourmet and green boiling products. s are relatively low if not irrigated. Maturity is considered early (only 5 later than CHAMPS). This variety is moderate susceptible to susceptible to TSWV, CBR and Sclerotinia Blight. CHAMPS: CHAMPS is a large-seeded Virginia-type peanut with a runner growth habit. It is the earliest maturing variety for the Virginia- Carolina region. s at early digging ( days after planting in Virginia) are high, and pod size, shape and color are suited for in-shell market. If an early frost advisory is in effect, CHAMPS can be harvested 10 days earlier than NC-V 11 with no reduction in yield. It is less susceptible to TSWV than most Virginia-type cultivars, but is susceptible to CBR and Sclerotinia blight. High yields and favorable pod characteristics were observed across years and locations and showed good tolerance to growth factors, similar to Bailey.
