ND-307 (Reg. no. CV-296, PI655297) is a new medium-early maturing, high-yielding pinto bean (Phaseolus vulgaris L.) cultivar adapted to the northern Great Plains. This cultivar was developed by North Dakota State University (NDSU) and released in 2008 by the North Dakota Agricultural Experimental Station (NDAES). ND-307 has a Type IIIa growth habit, but it may show a type IIb growth habit in some environments. ND-307 possesses intermediate lodging resistance and exhibits good and synchronous plant dry-down prior to harvest. ND-307 has commercially acceptable visual seed traits (size, shape, and appearance). However, one particular feature of ND-307 is the absence of the yellow seed corona. Instead, the corona is light-orange and its color intensity is slightly variable among seeds. Although the yellow corona is sometimes considered an important quality indicator for the dry bean market, it is not critical for other end-uses. ND-307 has intermediate resistance to the rust races commonly found in the region, with the exception of the new, recently discovered, race (20-3). ND-307 is also resistant to Bean common mosaic virus, but it is susceptible to the necrotic strain (NL-3). When averaged across 21 yield trials in which ND-307 was grown along with three commercial checks, ND-307 produced yields similar to Buster but out-yielded Maverick and GTS-900 by 7 and 9%, respectively. This cultivar represents a new and better alternative for pinto bean growers of the northern Great Plains. |
