Analysis of 32,574 papers published by USA, UK, China, India and Brazil in the field of 'plant genetics and breeding' research during 2005-2009 indicates that USA produced the highest number of publications followed by China. The impact of research output as seen by the values of different impact indicators is highest for UK. The sub-domains of emphasis of research shifted in 2009 as compared to 2005 for all countries. India contributed about 9 percent to the world publication output. Indian output formed a part of the mainstream science as seen by the pattern of publication and citation of the research output. The total Indian output originated from 1,806 institutions located in different parts of the country. About 41 percent of the total Indian output was concentrated among 23 institutions. Among the institutions, international institutes located in India had the highest impact.
