High yielding variety seeds are known for their resistance to insects and diseases and ability to produce high yields. These seeds are superior in quality and promote abundant and healthy crop production. The high-yielding seeds exhibit resilience against floods and droughts, resulting in better-quality yields. [5]
Borlaug's colleagues at the Consultative Group on International Agricultural Research also developed and introduced a high-yield variety of rice throughout most of Asia. Land devoted to the semi-dwarf wheat and rice varieties in Asia expanded from 200 acres (0.8 km 2) in 1965 to over 40 million acres (160,000 km 2) in 1970. In 1970, this land ...
These variety names are now largely abandoned, but are still sometimes used for distinctive types of wheat such as miracle wheat, a form of T. turgidum with branched ears, known as T. t. L. var. mirabile Körn. The term "cultivar" (abbreviated as cv.) is often confused with "species" or "domesticate". In fact, it has a precise meaning in botany ...
The varieties of wheat created through these methods are in the hundreds (going as far back as 1960), more of them being created in higher populated countries such as China. [150] Bread wheat with high grain iron and zinc content has been developed through gamma radiation breeding, [152] and through conventional selection breeding. [153]
The wheat grain classes used in the United States are named by colour, season, and hardness: [7] [8] [9] Durum – Hard, translucent, light-coloured grain used to make semolina flour for pasta and bulghur; high in protein, specifically, gluten protein. [8] [9] Hard Red Spring – Hard, brownish, high-protein wheat used for bread and hard baked ...
Since the induction of the International Maize and Wheat Improvement Center triticale breeding programme in 1964, the improvement in realised grain yield has been remarkable. In 1968, at Ciudad Obregón, Sonora, in northwest Mexico, the highest yielding triticale line produced 2.4 t/ha. Today, CIMMYT has released high yielding spring triticale ...
Hard red winter wheat (HRW) 40%: High plains, extending from Texas through the largest producing state, Kansas, and continuing all the way north to the Dakotas and Montana. [18] [19] Used mainly in flour production Hard red spring wheat (HRS) (also has a sub-classification of Dark Northern Spring Wheat [16]) of high protein value: 20%
A second strategy is to hybridize wheat with T. intermedium to create a strain of wheat that mimics T. intermedium ' s resistance and perenniality but retains wheat's seed size and yield. In other words, this second strategy gives wheat more T. intermedium-like characteristics. Researchers hope that these two strategies will progress and meet ...
