\nWhile both Asian and African cultivated rice varieties have distinct strengths, crossing them often produces offspring with sterile pollen and low yields.
\nA research team has now identified three genes that act as a barrier to reproduction \u2013 and also a possible way round the problem.<\/p>\n
