Product Description

The phenomenon of heterosis, also referred to as "hybrid vigor," underlies much of the improvement in crop yields achieved in the 20th centruy, in a range of crops including the vegetable crops.  The exploitation of heterosis in crop production is of vital importance to face the challenge of providing food and nutritional security for an ever-increasing human population.  Investment in hybrid technology is of particular relevance for developing countries, where feeding the existing population in the face of decreasing amounts of agricultural land and a declining resource base, already poses formidable problems.  This is a real option to meet the huge production increases that are required in the decades ahead.

The effective use of heterosis has fostered the development of worldwide seed industry.  Rapid advances in plant breeding and associated seed production technologies have served to enhance the competitiveness of hybrids by increasing crop and seed yield per hectare, reducing the costs involved, and improving seed quality.
