'pubescent t 611.' J. Genet. 51: 582-585. 



The gene controlling hairiness in the Upland variety 'Pubescent T 611' 

 was transferred to Sakel and shown to be identical with the G. tomentosum 

 gene H 2 .

group. J. Genet. 52: 186-198. 

 Three types of genes in Gossypium were involved in the genetic control of 

 pubescence to give jassid resistance on the abaxial surface.

RESISTANCE OF EXPERIMENTAL COTTON STRAIN 1514 TO THE BOLLWORM AND 



cotton fleahopper. J. Econ. Ent. 59: 393-395. 

 Resistance of a glabrous and nectary-free experimental Gossypium sp. 

 (strain 1514) to insect attack was evaluated. Lower populations of Helwthis 

 tea, and Pseudatomoscelis (= Psallus) senatus (Reuter), were found on this 

 cotton than on commercial varieties.

COTTON STRAINS RESISTANT TO THE COTTON FLEAHOPPER. J. Econ. Ent. 61: 



661-664. 

 The glabrous character in strains of Gossypium hirsutum suppressed pop- 

 ulations of Pseudatomoscelis seriatus below economically damaging levels 

 and was as effective as some recommended insecticides.

IMPROVED COTTON STRAINS RESISTANT TO THE COTTON FLEAHOPPER. J. Econ . 



Ent. 63: 1101-1103. 

 Pubescent strains of Gossypium hirsutum (homozygous for genes H 2 H 2 ) 

 had significantly more mirids {Pseudatomoscelis seriatus (Reuter) ) than 

 those with the normal complement of trichomes (homozygous for genes 

 H,H,).

LIOTHIS" POPULATIONS WITH GLABROUS COTTON STRAINS. J. Econ. Ent. 64: 



486-488. 

 Use of glabrous strains of Gossypium spp. with the resultant decrease in 

 Heliothis oviposition could delay the need for insecticides, and the strains 

 might permit other biological factors to be utilized more effectively.

J. Agr. Sci. 8: 43-68. 

 Resistant lines of Gossypium sp. had a dense cover of long stellate hairs 

 along the entire length of the midrib. Only plants with long, dense pubescence 

 over all of the midrib should be used in breeding programs for resistance to 

 Empoasca maculata Evans.
