VARIETY FORMS FOR BUSH KIDNEY BEANS. 



23 



grown no American variety of Kidney bean contains less than four 

 seeds. 



Position of seeds in green shell pods (very crowded, crowded, fairly 

 close, somewhat separated, fairly separated, much separated). — The 

 position of seeds in a bean pod varies from the tightly crowded con- 

 dition of Red Valentine to the much separated condition of Rogers's 

 Lima Wax and Tennessee Green Pod. 



Ease of thrashing dry pods (very easily thrashed, fairly easy to 

 thrash, somewhat hard to thrash, hard to thrash). — Ease of thrashing 

 is largely determined by the amount of fiber in bean pods. Thin- 

 walled, tough-podded field varieties seldom wrinkle or shrivel tightly 

 about the seed or break up into sections when thrashed, as do many 

 of the fleshy-podded garden varieties. 



Size of dry seeds (very small, small, small-medium, medium, large- 

 medium, large, very large).— Of kidney beans the small-seeded varie- 

 ties, like Navy Pea, produce about 2,200 seeds to the pint, the medium- 

 seeded varieties, like Golden Wax, about 1,100, and the large-seeded 

 varieties, like Improved Goddard, about 550. Bush Multiflora, 

 Scarlet Runner, and White Dutch Runner produce about 250, Hen- 

 derson's Bush Lima about 1,100, Burpee's Bush Lima about 320, 

 and Dreer's Bush Lima about 450 seeds to the pint. Although the 

 size of the seed is generally quite uniform in the same variety and 

 varies but little from the illustrations given in this bulletin, they are 

 nevertheless often affected by unusual seasons, locations, and soil con- 

 ditions, those grown in very poor soil and during dry seasons often 

 being but half the size of those grown in unusually damp locations 

 and seasons. 



Length of dry seeds (extremely slender, slender, medium, somewhat 

 short, short, very short). — The shape of dry seed is a fairly constant 

 feature which varies but little with season and conditions. Some 

 kidney sorts, like Ruby Horticultural Bush, are almost as broad as 

 long, while others, like Longfellow, are several times greater in length 

 than in cross section. 



Cross sections of dry seeds (very flat, flat, flat-oval, oval, round- 

 oval, round). — The shape of the cross section of seeds is a fairly 

 constant varietal feature and is usually an indication of the shape of 

 the pods. 



Ends of dry seeds (very rounded, rounded, rounded to truncate, 

 truncate, decidedly truncate). — The shape of the ends of seeds depends 

 largely upon the position of the seeds in the pod, those which are 

 very crowded in the pod being generally square at the ends, while 

 those which are well separated in the pod are usually rounded at the 

 ends.
