781. Anonymous. Sobre a floragao da mangueiro. [The blooming of the mango.] Bol. 

 Agric. [Nova Goa, Portuguese East India] 1: 207-210. 1919. — The causes of non-flowering in 

 the mango (Mangifera indica) are discussed, inchiding excessive heat and hiimidity, insects, 

 and overproduction the previous year. Remedies for certain of these conditions are outlined.

782. Anonymous. Two new raspberries. Jour. Pomol. 1 : 243. 2 pi. 1920. — Two promis- 

 ing new varieties of red raspberry are described, the Pyne's Royal and the Park Lane, both 

 originated by Mr. Pyne of Topsham, Devon, and introduced in 1912 and 1913. — L. //.

784. Anthony, R. D. Has the orchard survey a place on the research program? Proc. 

 Amer. Soc. Hort. Sci. 17: 174-178. 1920 [1921]. — This paper discusses the manner in which 

 a pomological survey, dealing chiefly with apples, was conducted in Pennsylvania. The 

 author concludes that, inasmuch as the survey brought the College and Station staff into close 

 contact with actual field conditions in the state, the staff was thereby in a much better position 

 to plan and conduct its research work so as to be of the greatest value to the state. This 

 would not have been possible without the intimate knowledge of the problems which were 

 brought out by the survey. — H. W. Rickey. 



785. Auchter, E. C. A preliminary report on apple and pear breeding in Maryland. Proc. 

 Amer. Soc. Hort. Sci. 17: 19-32. 1920 [1921]. — This is a preliminary report covering the in- 

 vestigations in apple and pear breeding during the past 15 years. The pear crosses are mainly 

 between Keiffer and other standard varieties. In most of the apple crosses one or both parents 

 were from early varieties. Since many of the pear and apple seedlings have not fruited, a 

 detailed study has been made only of the results secured from the 1907 early-apple crosses. 

 The varieties intercrossed have been chiefly Early Ripe, Yellow Transparent, Williams, 

 Red June, Astrachan, and Early Harvest. Seeds have also been secured from these varieties 

 when open pollinated. The results show that certain crosses set fruit better than others; 

 that more seeds per apple were produced from some crosses; that the percentage of germina- 

 tion varied considerably, and that in certain crosses a greater percentage of seedlings died, 

 whether from poor environmental conditions or weak constitutional vigor. There is a sugges- 

 tion that the factor, or factors, for long length of apples is dominant over the factor, or factors, 

 for shorter length, those for red color over those for yellow color, and those for acid or sub- 

 acid flavor over those for mild sub-acid or sweet flavor. The fruit of seedlings has about the 

 same ripening period as that of their parents. Of the 166 crossed seedlings, 24 appear to be 

 promising, of the 90 seedlings produced from open pollinated fruit, only 2 are promising. 

 Williams seems to be a good variety for early-apple breeding. Of the cross, Williams X 

 Transparent, one seedling, ripening as early as the earliest Transparents, is very promising. —

 of tropical fruits. The coconut and the date.] Rev. Agric. [^lexico] 5: 579-5S1. 3 fig. 1920. — 

 The possibilities of growing the date and coconut commercially in Mexico are discussed. —

788. Balme, Juan. La viticulture en Mexico. [Viticulture in Mexico.] Rev. Agric. 

 [Mexico] S : 581-583. 2 fig. 1920. — In order to encourage the grape growing industry in Mexico, 

 the Department of Agriculture has decided to distribute a million plants of selected varie- 

 ties. For comparative purposes, statistics of the California industry are given. — John A. 

 Stevenson.
