Description Sorghum (Sorghum bicolor [L.] Moench) is grown both in rainy (Kharif) and postrainy
(Rabi) seasons in India for multiple uses. Of the total sorghum area of 6.5 m ha,
postrainy sorghum is grown on ~ 4 m ha area in the black soils under receding soil
moisture, after the cessation of rains. The majority of postrainy sorghum production is
concentrated across the states of Maharashtra, Karnataka and Andhra Pradesh (Trivedi,
2008; Rana et al., 1999; Hosmani and Chittapur, 1997). Postrainy sorghum growing
areas are characterized by low rain fall, low temperatures at flowering time and
terminal drought and most of the times sorghum is the only crop option for meeting the
food and fodder needs of communities in these areas (Murty et al., 2007; Pray and
Nagarajan, 2009; Belum Reddy et. al., 2012; Kholova et al., 2013). Because of these
constraints the productivity of postrainy sorghum is low (grain yield ~0.7 t ha‐1).
However the grain and stover quality obtained from postrainy sorghum is preferred by
the farmers and markets, therefore of higher value. Across postrainy sorghum
ecologies, the landrace cultivars possessing white bold lustrous grains, with photoperiod
sensitivity, cold tolerance, shoot fly resistance and terminal drought tolerance, like M
35‐1, Dagadi are popular with farmers. There are some improved varieties developed by
Indian national program but they are not available to most farmers. The seed
replacement ratio is very low (20%) (Fig 1). Further, the market opportunities for grain
and fodder are limited restricting it to a subsistence production system. This paper deals
with the current status of postrainy sorghum seed systems and innovative approaches
to improve the quality seed availability to farmers.
