78 THE PEANUT— THE UNPREDICTABLE LEGUME 



8. Leaf rachis presence dominant to absence, complementary (15:1), Hayes 

 (30). 



9. No constriction on pods, double dominant, two factors, Badami (2). 



10. Leaflet size intermediate in Fi and wide range in F2, Badami (2). 



11. Large pod dominant to small, three factors, Badami (2). 



12. Pericarp thickness, five factors, thin pericarp linked with pygmy seed, 

 Badami (2). 



13. Deep reticulations on pericarp dominant to shallow, at least four factors, 

 Badami (2). 



14. Hairy stem dominant to less hairy, Badami (2) ; 3 :1, Patel (48). 



15. Three or many-seeded pods dominant to less than three-seeded, at least three 

 factors, Badami (2). 



16. Long growing season dominant to short, Badami (2) ; 3:1, Patel (48). 



17. Early fading flowers dominant to late, Hayes (30). 



18. Deeply colored corolla dominant to light, Hayes (30). 



19. Red color on leaflet vein dominant to its absence, Hayes (30) . 



20. Sine leaf shape dominant to Valencia shape, Hayes (30). 



21. Required rest period of seeds partially dominant to its absence, Stokes and 

 Hull (69). 



22. Variegated seed due to rupture of seed coat as found in A. namby quarae 

 partially dominant to its absence in A. hypogaea, Stokes and Hull (69). 



23. Sterile dwarf, 15 :1, Patel (48). 



24. Branching over non-branching, 3:1, Patel (48)." 



Hull's own work was chiefly directed toward analyzing the genetic 

 behavior of dormancy in peanut seeds. In addition, however, he reported 

 the following results on other characters : 



1. In crosses of Spanish and Runner peanuts long by short seeds were intermedi- 

 ate in the hybrid. The results indicated that seed shape was largely con- 

 trolled by physiological maternal influence rather than by embryo genotype. 



2. Russet seed coat of Runner peanuts dominant to tan in Spanish. 



3. Yellow seedlings from certain crosses behaved as full recessives in a duplicate 

 gene complex with green fully dominant. The assignment of genetic formulae 

 with respect to this character cuts across some interesting taxonomic lines, 

 for Hull states that the following genetic formulae and varietal association 

 was indicated from his study of this character: L1L1I2I2 (Spanish) L1I1I2I2 

 (Runner group and A. nambyquarae and LiLiL2L2 (Valencia and A. 

 Rasteiro*.) 



4. Valencia plant type was found in the progenies of several crosses of Spanish 

 X runner. It behaved as a recessive set of duplicate genes where each parent 

 carried alternate recessive and dominant pairs. 



5. Male sterile brachytic dwarf appeared in the progeny of Virginia Runner x 

 Tennessee Red and behaved as a simple recessive. 



6. The regressions of twenty-two separate characters as dependent variables, and 

 rest period of seeds, seed shape, seed coat color, yellow seedlings, and Valencia 

 plant type as independent variables were analyzed. No significant regressions 

 were found. 



* A. Rasteiro = a form of A. hypogaea.
