POSSIBLE CORRELATIONS CONCERNING POSITION 

 OF SEEDS IN THE POD 



Byron D. Halsted' 



This study was made with the Henderson Lima bean on a 

 block of ground one-fortieth of an acre. Nine rows of lo hills each 

 were planted 5 seeds to the hill in the manner shown in table I. 



TABLE I 



Table I shows that seeds from the middle of 3-seeded pods had 

 the highest viabihty, and that of those from the base of 2-seeded 

 pods nearly one-half failed to produce plants. The average 

 viability of the 3 rows planted with basal seeds was 58 . 6 per cent, 

 the next lowest 66.6 per cent in the rows planted with tip seeds, 

 and the highest viabihty 69.3 per cent, obtained in the rows 

 planted with seeds from the middle of 3-seeded and 4-seeded pods. 



Table II shows that the pods are chiefly of the 3-ovuled type, and 

 that the others are somewhat equally divided between the 2-ovuled 

 and 4-ovuled pods. The yield of pods from seeds of 2-ovuled pods 

 is 15.61 per cent less than the average yield from seeds of 3-seeded 

 and 4-seeded pods. 



Pods from plants grown from seeds borne in the basal position 

 numbered 1463, from seeds from middle position 1735, and in the

 brief biographical sketch appears in the Botanical Gazette of February 1919.
