Book Description
Excerpt from Improving Wheats Selection Any variety can be improved by careful and methodical selection. This method has been in vogue for many ages, and it is to it that we largely owe the gradual improvement that has taken place not only in wheat but in all cultivated plants. There is still plenty of room for improvement, however, and in the present chapter, we point out in particular not only the possibilities ahead, but give plain directions that will enable anyone so inclined to follow up our suggestions. All artificially obtained varieties tend to deteriorate as soon as the care which produced them is withheld, so that even if it were no longer possible to improve the wheat-plant by selection, it would still behove us to practise careful selection for the purpose of keeping up the quality we have already secured. While it is true that selection can be carried on in the field as ordinarily cultivated, and that this is the method anciently practised and one that is still in vogue, we strongly recommend the putting aside of specially selected and specially tilled land for the growth of plants from which to select.

Book Description
Excerpt from The Basis for the Improvement of American Wheats This work was continued, but in the meantime careful studies were being made in the several wheat districts with a view of determining the particular needs Of each. In some districts greater hardiness of winter sorts is required; in others, varieties with a particularly tena cions chaff; in others, stiffer straw; in others, drought resistance, and so on. Varieties bred for North Dakota and Minnesota are of no value for California, and the best varieties for Texas would be useless in Montana. But aside from these considerations a knowledge Of the different botanical groups of wheats is necessary, in order to have at command all the sources from which may be drawn the qualities required for different districts.

Book Description
Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Book Description
Excerpt from The Selection of Seed-Wheat In connection herewith it should be stated that the highest results can only be obtained when the seed is selected from pro ductive individual plants, and that under favorable conditions even small perfect seeds from productive plants may be better than large seeds from unproduc tive plants. The main influence of large grains selected by simple sieve grading. Will be in giving the plants a more Vigorous start in life, which of itself is of extreme importance. Other things being equal it is entirely fair to pre sume that the crops which are placed under the most. Favorable environment are going to give the best returns. It has been shown that, m general, the more vigor ous plants (that is, those having the largest spikelets) contain the larger grains, so that even: in selecting the grains by simple Sieve separation the bulk of the larger grains would come from the more vigorous plants, and thus there would be, in a measure at least, a selection from vigorous plants.

Book Description
Excerpt from Milling Tests of Wheat; New Varieties of Cereals: Evidence of Dr. Charles E. Saunders, Experimentalist, Dominion Experimental Farms; Before the Select Standing Committee on Agriculture and Colonization, 1905 Besides improving wheat, we have of course endeavoured to improve our varieties, by cressing and selection, and this work has given rise to a number of new sorts. I have referred already to the introduction of Ladoga wheat, and to the crosses which were made between that variety and Red and White Fife, the object being to combine, as far as possible, the quality of the Fife wheats with the earliness of the Ladoga. Among these cross-bred sorts Preston, Stanley, Huron, and Percy are attracting most attention, and I have here samples of the our of two or three of these varieties.

Book Description
Excerpt from On the Varieties, Properties, and Classification of Wheat This little w'ork On the Varieties, Properties, and Classification of Wheat, by John Le Couteur, Esq., Colonel of the let Regiment of Jersey Militia, and aide-de-camp to the King, 1836) should. Be in the possession of every cultivator of wheat. We do not regard itas exaggeration to say that it will do more for the agriculture of the empire than has been effected by all the societies instituted for the purposes of agricultural improvement put together. Colonel Le Couteur has struck into the right path, and not only has exhibited that care and discrimination which alone Can render the culture of wheat com pletely successful, but has pointed out the means by which all the Cerealia may be managed with the fullest benefit to the grov'ver and to the public. To our surprise he has dedicated his work to the Central Agricultural Association of Great Britain and Ireland - an Association evidently not brought together on the principles on which our author's experiments have been founded; but for the purpose of keeping up rent unjustly, and tampering with the currency to effect that end; deeming the filling of landlords' pockets at the expense of the tenantry a fit object for legislative interference. Our author is a member of the Association and it is astonishing that he should address it with adulation while its objects are purelyselfish, and his own to bring about amelioration in the only manner that is rational-via, by select ing and improving the best varieties of corn, and cultivating them in the most economical manner.

Book Description
Excerpt from How to Increase the Yield of Wheat in California Fig. 1.4birdseye View of California Cereal Station, Sacramento Valley. Fig. 2. - Genera1 view of grain plats on the Tulare Station, 1908. The investigations covered by this report are in general based. Upon results and observations covering a long period. For a limited time a portion of the work was conducted in co-operation with the Bureau of Plant Industry of the United States Department of Agriculture. Both the field and laboratory investigations have covered a wide range. They embrace the relative value of deep vs. Shallow plowing, early vs. Late seeding, drill vs. Broadcast seeding, trials with fertil izers, the effect of certain rotation schemes, the improvement of the soil through green-manuring, moisture conservation, the treatment of. Grain for the prevention of smut, the value of exchanging seed, clean ing the land from weeds both by cultural methods and the use of chemical sprays, and finally, variety trials and the development of better types of grain than those commonly grown. In the study of the general question of environmental influence upon the quality of wheat, and also the selection work involving an increase of the gluten content, there has of course been a large amount of chemical work required. Questions involved along these lines have been the influence upon the gluten content of the length of the growing period, of the time of harvest, of the time of seeding, of the time the wheat plant receives its moisture, the influence of sunshine and of the composition of the soil. The environmental question as affecting the gluten content will be the theme of a separate report. In this report an effort has been made to so correlate the cultural results and observations that they may be of immediate benefit to the California grain growers, in effecting improvement in soil fertility, increasing the yield of grain, and. Improving the milling quality of the grain produced. It should be said that these results should be considered as simply the foundation for more extensive work. The element of time is an all-essential one for the solution of such problems as these. This would be true even though the problem was merely the develop ment of grain giving higher yields, but, with the introduction of the problem of increasing the gluten content, the element of time is of even greater importance.
