1JH!>1 FIELD CROPS. 239 



A survey was made of lis fields in a representative strip of country aer o — 

 the State from north to south to ascertain tiie type of <«ats grown. Thirteen 

 varieties were Identified, Lincoln, Swedish Select, Sllvermine, and Belyak 

 being found on 28.2, 26.3, 13.G, and 11.3 per cent of the farms visited, re- 

 spectively. 



The relation between color and other characters in certain Avena crosses, 

 H. H. Love and W. T. Craig (Amcr. .Vat., 52 (1918), No. 'A, pp. 869-883).— 



This paper, a further contribution to the subject from the department of plant 

 breeding of Cornell University working in cooperation with the Office of Cereal 

 Investigations, U. S. Department of Agriculture, presents a discussion of the 

 relation of color to awns, pubescence, and wild base as observed in a cross be- 

 tween A. fatua and A. satiru, variety Sixty Day, already described In detail 

 (E. S. R., 39, p. 234). 



The data are held to indicate that there is a definite relation between the 

 color of the glume and the production of awns, the black and gray oats pro- 

 ducing awns in varying amounts, while few or no awns were produced on the 

 yellow oats. A form of A. fatua was observed having a pubescence factor linked 

 with a factor for black color and another pubescence factor independent of any 

 color factor, which in the absence of an inhibitory effect in the yellow oats 

 would be expected to produce 15 pubescent to 1 nonpubescent form in the F t 

 generation. A second form was also found having only one factor for 

 pubescence, which when crossed with a white oat resulted in all the nonblacks 

 being smooth, indicating that the pubescence factor is linked with the black color. 

 Forms having two factors for pubescence gave both pubescent and smooth non- 

 blacks. The theoretical expectations from crosses of these two forms with 

 yellow and white oats and the actual results obtained are discussed. It is also 

 stated that even through the F« generation no yellow oat has been found with 

 a wild type of base. 



The authors state that they do not claim that yellow color in oats will inhibit 

 the production of awns, pubescence, and wild base, but that yellow color as ex- 

 hibited in the series studied has done so. In crosses using other yellow forms, 

 it was found possible to obtain the yellow pubescent form and yellow forms 

 with the wild base. 



[Fertilizer experiments with oats], W. G. R. Paterson (West of Scot. Agr. 

 Col. Ann. Rpt.. 14 {1917). pp. 285-2J t 6). — Rather limited fertilizer experiments 

 with oats conducted at the West of Scotland Agricultural College during 1912 

 to 1914, inclusive, are described. Acid phosphate and kainit applied at the 

 rate of 2 cwt. per acre, together with either 134 lbs. of nitrate of lime or 87 

 lbs. of sulphate of ammonia, resulted in an average yield of 54.5 bu. of grain 

 and 4,312 lbs. of straw, as compared with 41.25 bu. of grain and 3,164 lbs. of 

 stfaw from the untreated check.

Culture and fertilization as affecting the oil content of peanuts, H. S. 

 Silayan (Philippine Agr. and Forester, 6 (1917). Xo. 2-8, pp. S4-97, fig. 1).— Six 

 standard varieties of peanuts, designated as American, Big Japan. Kinorales, 

 Native Lemery, San Mateo, and Montalban, were grown on field plats receiving 

 ridge and flat cultivation and applications of stable manure, wood ashes, and 

 manure and ashes combined, and the effect of the different treatments on 

 yield and oil content noted. 



The American variety was first in yield on the check plat with 3.783 lbs. 

 pei- hectare (about 1,531 lbs. per acre) and San Mateo second with 3,648 lbs.
