Leaf scald caused by Xanthomonas albilineans in sugarcane is one of the most important diseases around world since it causes severe losses both agricultural and industrial yields. In Cuba, resistance to this disease considered a major selection criterion within breeding program. The aim work was detect cultivars with stable reaction X. using additive main effects multiplicative interaction (AMM...

Farmers in many regions of the world grow a horticultural or grain crop between sugarcane (a complex hybrid of Saccharum spp.) cycles. This additional crop often requires higher amounts of P or K fertilizers than does sugarcane. Some sugarcane growers in Florida precede 2to 5-year cycles of sugarcane with one crop of spring-harvested sweet corn (Zea mays L.). A disadvantage perceived with this ...

Mantel tests of matrix correspondence have been widely used in population genetics to examine microevolutionary processes, such as isolation-by-distance (IBD). We used partial and multiple Mantel tests to simultaneously test long-term historical effects and current divergence and equilibrium processes, such as IBD. We used these procedures to calculate genetic divergence among Eugenia dysenteri...
