Hybrid pigeonpea seed production manual

Seeds and Plant Production The time required to reach maturity can vary greatly due to seed variety, temperature, and photoperiod. C. cajan is a short-day plant, requiring a daylight length of hours to initiate flowering and seed production (Cook et al., ).

While open pollinated maize seed production is relatively straightforward, hybrid seed production requires additional field practices that are critical to success.

Hybrid seed production has started in pigeon pea, maize, sorghum, pearl millet and caster during Besides, Raj Vijay seed and planting materials are. developed in India and the hybrids produced with these lines have high heterosis. The use of highly stable CMS will reduce the cost of hybrid seed. However, the hybrid became so popular that synthetic production was stopped. Very little certified seed of pigeon pea, cowpea, sorghum, millet or green.
