Distinctness, uniformity and stability (DUS) characterization on phenological traits and assessing the diversity of inbreds in maize (Zea mays L.)

Maize is one of the economic crops of global importance. Protection of Plant varieties and Farmers Right Act (2001) insists on Distinctness, Uniformity and Stability (DUS) characterization of extant, farmers and new varieties and recommends the registration of varieties for any one specific novel character. Studies initiated to develop morphological characters in seventeen inbreds including 16 domestic inbreds (UMI...

How far do egg markets in India conform to the law of one price?

Growing demand for eggs in India is also accompanied by its production at six per cent compound annual growth rate. The law of one price states that in an efficient market, all identical goods or commodities should have a single price. Johansen’s cointegration test was done to identify whether spatially separated egg markets in India share a common linear deterministic trend and the law of one price holds true....
