Technical Abstract: 'Kodiak' pinto bean (Phaseolus vulgaris L.) was derived from a cross made in 1992 between the pinto and great northern bean breeding lines, P90557 and G91213, respectively. 'Kodiak' was developed cooperatively by the Michigan Agricultural Experiment Station and USDA/ARS. 'Kodiak' was released in 1998 and is an upright-with a tendency to lodge-high yielding, midseason, disease resistant pinto bean cultivar adapted to Michigan and the Great Lakes Region of the U.S. 'Kodiak' was yield tested (26 locations) from 1994 to 1997. 'Kodiak' averaged 2,860 kg ha**-1 yield and outyielded 'Aztec' by 11% over 18 locations, 'Othello' by 10% over 21 locations and 'Chase' by 5% over 11 locations. 'Kodiak' averaged 48 cm in height and exhibits a Type II indeterminate growth habit with moderate lodging resistance. 'Kodiak' has white flowers and blooms 51 days after planting. 'Kodiak' matures 94 days after planting and is 7 and 2 days later than 'Othello' and 'Aztec', respectively but 2 days earlier than 'Chase'. 'Kodiak' has the typical flat, beige mottle seed of pinto beans; its seed averages 42g 100 seed**-1. 'Kodiak' has acceptable canning quality and does not differ from other commercial pinto bean cultivars for cooked color, texture and the hydration and washed drained weight ratios. 'Kodiak' is the first pinto bean cultivar to have a protected I gene resistance to bean common mosaic virus (BMCMV). The I, bc-1**2 gene combination, gives 'Kodiak' protection against the temperature insensitive necrosis-inducing strains of BCMV, namely NL3 and NL8. 'Kodiak' has the Ur-3 and Ur-6 rust resistance genes which conditions resistance to Races 47 and 53 and all indigenous races in Michigan of Uromyces appendiculatus (Pers.: Pers.) Unger. 'Kodiak' is tolerant to Fusarium root rot disease.
