Abstract

The parental lines, DPC-9 (female) and TMV-5 (male) of castor hybrid (YRCH-1) were sown in 3:1 ratio with
six sowing dates and four different spacings. The highest seed yield was recorded from first fortnight of November or second fortnight of November adopting either 120 cm x120 cm or 150 cm x 120 cm. The genetic contamination in terms of interspersed male flowers present in the female lines was minimum during the Novembersowing.
