Abstract

Castor (Ricinus communis L.) is an annual or perennial flowering non-edible versatile oilseed species of Euphorbiaceae family having sexually polymorphic species with unisexual flowers, either male or female mostly arranged as monoecious and occasionally pistillate spike. Three types of pistillate mechanism are present in the castor i.e. N, S and NES types. These mechanisms are utilized for the development of new pistillate lines in castor. The development of a new pistillate line in castor is a highly tedious and changeable job. ANDCP 1601 is a new NES type pistillate line that was identified from the segregating population of cross between ANDCP 06-07 × ACP 1-06-07 during 2008-09 at Regional Research Station, AAU, Anand. The pistillate line evaluation trial was conducted at two locations viz., Anand and Derol during kharif 2021-22 and 2022-23. Seed yield of ANDCP 1601 was found 11.23 and 18.78 per cent higher than SKP 84 during 2021-22 and 2022-23, respectively. The proposed line has distinct morphological characters viz., green stem color, triple bloom, long peduncle, semi compact spike with spiny capsule, early maturing and late revertant type. At RRS, AAU, Anand tested under wilt screening plot against the wilt susceptible check i.e. JI 35 and it is found highly resistant reaction against wilt. Therefore, the newly developed promising pistillate line ANDCP 1601 can be effectively utilized in hybrid breeding program for developing high yielding, green stem hybrid in castor.

Conclusion

The newly developed line ANDCP 1601 is having NES type pistillate mechanism with distinct morphological characters like green stem, triple bloom, semi compact spike, early maturing, late revertant and highly wilt resistant reaction.
