Var. Hopi. 



Barrons 1938 (12): Hopi 155 was partially resistant in the field, occasional 

 plants susceptible; definitely susceptible in greenhouse seedling test, 

 occasional plants partially resistant. Alabama. 



1938: 96 California station strains Nos. 5987, 5988, and 5922 more 



resistant at Auburn than Hopi 155 (1 season). Alabama. 



1939 (13): Numerous larvae entered root tips of seedlings and of 



"adult plants" (Hopi 155) heavily inoculated in greenhouse; young roots 

 of seedlings and of plants 2, 4, and 8 weeks old "developed root knot to 

 the same degree" as the susceptible Henderson Bush lima; 8 weeks later 

 galls on Hopi 155 were "for the most part . . . nothing more than slight 

 swellings . . . There were no signs of decay." Alabama. 



California Agricultural Experiment Station 1936 (29): Hopi 155 is 

 rapidly replacing other small-lima-bean varieties; high yield; more 

 resistant to heat, nematodes, and other pests than varieties formerly 

 planted. Hopi No. 5989 is superior to No. 155 in yield, quality, and 

 nematode resistance. [Calapproved 97 seed of No. 5989 is distributed by 

 A. Milani, Tracy, Calif., according to the Stockton, Calif., "Record" for 

 January 22, 1938.] 



Isbell and Barrons 1938 (117): Hopi No. 155 and other California station 

 Hopis (tested 5 years) are heavy yielders and notably more resistant 

 than common varieties, but less resistant in Alabama than is Alabama 

 No. 1 (P. vulgaris). 



Ktng 1937: 98 Many limas collected from the Hopi country, some much more 

 resistant than No. 155, but not wanted by the trade because mottled. 

 Arizona. 



Mackie, W. W. (quoted in California station Circular 330 (236, p. 12), 

 1933): Hopi No. 155, bred by W. W. Mackie, is highly resistant to root 

 knot, fusarium wilt, charcoal rot, and heat, but its nematode resistance 

 is not yet fixed; some vines, reverting, may even be killed. Hopi No. 

 20C0 is somewhat less resistant to root knot. 



(in letter, 1939) : Nematode-resistant Hopis now occupy much of the 



lima-bean area in California; a recent infestation is being checked with 

 Hopi, No. 5989; Hopis yield up to 40 or more sacks per acre; Hopis died 

 out, however, in 2 heavily infested areas. 



and Smith 1935 (153): Small lima grown for centuries by the Hopi 



Indians of Arizona shows heterozygosity from constant field crossing. 

 [No reference to nematode resistance.] 



Tennessee Agricultural Experiment Station 1936 (227): Showed high 

 resistance to nematode injury. 



Phaseolus vulgaris, common bean. (N, S) 



Frank 1885 (68): No infestation found; other hosts preferred (one planting). 



Germany. [In 1896 Frank (69) listed Phaseolus as a preferred host.] 

 Isbell and Barrons 1938 (117): Snap beans not seriously affected because 



grown daring the cooler months Alabama. 

 Watson, Goff, and Bratley 1937 (259): Selections for greater resistance 



are being made in a "resistant" strain of Kentucky Wonder from the 



Alabama station. Florida. 



Vars. Alabama No. 1 [now preferred] and No. 2, pole snap bean. 



Barrons 1939 (13): Numerous larvae entered root tips of seedlings and of 

 "adult plants" heavily inoculated in greenhouse; some 90 larvae entered 

 1 rootlet. [No report on later development of galls or of nematodes.] 

 Alabama. 



■ 1940 (13a): Resistance in Alabama No. 1 is probably inherited as a 



double recessive character. All the Fi hybrids between this bean and 

 Var. Kentucky Wonder showed characters of both parents — the antho- 

 cyanin pigmentation of the Alabama No. 1 and the susceptibility of the 

 Kentucky Wonder (14 seeds grown in greenhouse 22 days; 5 seeds in 

 field grown to maturity). In the F 2 and F 3 generations, grown in large 

 numbers, "intermediate" plants were not easily distinguished from the 

 completely susceptible segregates. Alabama.
