Abstract
In the year 1994-95 the area under Barley production in Pakistan was 165,000 hectares, while in that Sindh was 24,900 hectares. The Barley production in Pakistan was 164,000 tonnes, while in Sindh its production was 12,200 tonnes. In the year 1994-95 the yield per hectare in Sindh was 489 kgs, while its yield per hectare in kgs in Pakistan was 993 kgs.
Varieties
The varieties or cultivars are grown in Pakistan are Karan-4, Karan-19, Karan-201 and Karan 521 (huskless), Karan-280, Karan-15, Jyoti and K-125 (Hulled). Cytoplasmic male-sterility is not found so far so the production of hybrid variety is not so advanced.
Cultivated barley comprise chiefly two species, Hordeum vulgare L., six-rowed, and Hordeum distichon L., tow-rowed barley. The former species are grown more extensively than the latter. Cultivated barley have seven pairs of chromosomes. Two-rowed barley tend to tiller more strongly than the six-rowed type. In barley tillering continue after earing if nitrate and moisture supply are adequate.
The commercial varieties of barley may divided into three types according to their reaction to day-length and temperature. These are winter barley (low temperature requirements), spring barley and intermediate winter barley.
Barley is used extensively in the study of linkage relations, including resistance to certain diseases, as mentioned by Robertson, Wiebe and Shands (1955) cultivated barley is divided into three classes based on the character of growth; winter, intermediate and spring.
