S U M M A R YThe present structure of plant breeding and seed multiplication in India is highly centralized. Furthermore, only a small number of new varieties is officially released each year. The system therefore appears inappropriate for the requirements of the large proportion of Indian farmers located in risk-prone and highly diverse environments. An alternative strategy is described whose central feature is close matching of the characteristics of farmers' traditional rice varieties with those of advanced breeders' lines. A selection from these lines is then distributed in small quantities for on-farm trials managed by farmers themselves. If the success of these initial efforts is to be sustained, a more decentralized approach to breeding and multiplication will be necessary.D. M. Maurya, A. Bottrall y J.

R E S U M E NLa estructura actual de la fitotecnica y multiplicacion de semillas en la India esta sumamente centralizada. Es mas, cada ano se lanzan oficialmente solo un numero reducido de variedades nuevas. El sistema parece por lo tanto ser inapropiado para los requisitos de la gran proportion de agricultores hindues situados en entornos propensos al riesgo y muy diversos. Se describe una estrategia alternativa, cuya caracteri'stica central es la combination estrecha de las caracteri'sticas de las variedades tradicionales de arroz del agricultor con las de las li'neas avanzadas de los fitotecnicos. Se distribuye una selection de estas li'neas en peguenas cantidades para ensayos en la granja manejados por los mismos agricultores. Si el exito de estos esfuerzos iniciales ha de continuar, hara falta un enfoque mas decentralizado de la fitotecnica y multiplicacion.
