and breeding of cultivated plants.] (Translated from Russian by C.

Triticum timopheevii (Zhuk.), distinguished by the high degree of hairiness 



of its leaves and leaf sheaths, was highly resistant to seine I la frit in heavy 



fly infestations in the Maikopsk Region of North Caucasus.

 Varieties of Triticum with a smooth, hairless leaf-blade surface are unfa- 

 vorable for oviposition by Mayetiola destructor (Say).

leaf pubescence of field grown wheat: a deterrent to oviposition by 

 the cereal leaf beetle. J. Environ. Qual. 2: 333-334. 

 Leaf pubescence, a deterrent to oviposition by Oulema melanopus (L.), is 

 being bred into wheats in an attempt to replace insecticides as a means of 

 controlling damage by this insect. On the basis of number of eggs per 30.5 

 meters of drill row, each of three pubescent Purdue lines reduced the number 

 of eggs laid and the number of damaged leaves at least 94 percent compared 

 with a less pubescent cultivar, 'Arthur'.

the cereal leaf beetle. J. Econ. Ent. 59: 827-829. 



Wheats with highly pubescent leaves were largely avoided for oviposition. 

 A 14-chromosome wheat, Triticum persicum fuliginosum Vavilov, with high- 

 ly pubescent leaves, had great resistance to Oulema melanopus (L.).

the relation between silica in wheat plants and resistance TO HES-

 Certain varieties of Triticum had silicified hairs on the surface of the 

 sheath, and most of these varieties were susceptible to attack by Mayetiola 

 destructor.

 Leaf surface pubescence in Triticum aestivum L., was quantitatively inher- 

 ited; the gene action estimated on the square root scale was mainly additive.
