Introduction

    • The seed production of varieties and hybrids of vegetables should be carried out carefully in the region where these are well adopted. The climatic factors have direct bearing on the quality seed production. These includes, light (duration, intensity and photoperiod), temperature (low, moderate, high and very high), rainfall / snowfall (total as well as distribution) and wind (direction and velocity).
    • Climate is the most important factor and generally for seed production and dry temperate climate is most suitable. For example, seed production of cabbage is only possible in dry temperate areas where chilling requirements are met. Different vegetables need different climate for successful seed production and can be classified into temperate and tropical types. Climate may enhance bolting in the normal bulb crop of onion. Photoperiod also affects bulb crop and seed production in onion.
    • The various factors affecting quality seed production includes,
    1. Agro climatic factors / Ecological factors – edaphic and climatic factors
    2. Production factors
    3. Post harvesting handling of seed
    4. Seed quality control factors
