B. 2015-to till date at ICAR-Indian Institute of Oilseeds Research, Hyderabad, India

Focusing mainly on castor (Ricinus communis L.) improvement programme. Castor is a highly cross pollinated crop with 2n=20 belong to Euphorbiaceae family. It is primarily cultivated for it non-edible oil, extensively used in various industries and automobiles.

Products developed 

Hybrids Notified/Promising in AICRP (Castor) Trials (2018-2021)

1. Development of ICH-66 hybrid castor hybrid:  ICH-66 has been centrally notified vide S.O. No. & date: 3220 (E) 05-09-2019. It is a High yielding (1.56 t/ha), wilt and leafhopper resistant hybrid and notified for cultivation in rainfed castor growing regions of AP, Telangana, Karnataka, Tamil Nadu and Odisha. 
2. Development of ICH-5 (ICH-278 hybrid): ICH-5 hybrid has been centrally notified vide Gazette notified (S.O.No. 8(E)) dated 03.01.2022 for cultivation in Andhra Pradesh, Telangana, Karnataka, Tamil Nadu, Odisha and Maharashtra.

• ICH-5 recorded a weighted mean seed yield of 1671 kg/ha and weighted mean oil yield of 750 kg/ha pooled over 14 rainfed trials (2018-19, 2019-20 & 2020-21), which is                           21% seed yield superior over the national check GCH-8 (1378 kg/ha) 

               19% oil yield superior over the national check GCH-8 (630 kg/ha)

• ICH-5 recorded a weighted mean seed yield of 1753 kg/ha and weighted mean oil yield of 786 kg/ha pooled over 11 rainfed trials (2019-20 & 2020-21), which is 

                15.3% seed yield superior over the zonal check, ICH-66 (1521 kg/ha)

                15.6% oil yield superior over the zonal check ICH-66 (680 kg/ha)

• ICH-5 is also resistant to Fusarium wilt and Macrophomina root rot in sick plots. The proposed hybrid ICH-5 is also resistant/moderately resistant to leafhopper with a 0-2 hopper burn score compared to susceptible checks. 

Hybrids/varieties Promising in AICRP (Castor) Trials (2018-2021)

1. ICS-164  variety has recorded 33% (IVHT-2019-20) and 24% (AVHT-I, 2020-21) seed yield advantage over DCS-107  under rainfed conditions.
2. ICH-277 Medium duration) has recorded 1858 kg/ha, which is 15%  and 18% seed yield advantage over GCH-8 (1615 kg/ha) and ICH-66 (1571 kg/ha) respectively under rainfed conditions in IVHT-2020-21 and has been promoted to AVHT-I (2021-22) (5 locations)

Genetic Stock Registered/ in Pipeline

Pistillate line Development

New Pistillate Lines Developed (2018-2021)

1. Three diverse mutant pistillate lines have been developed Viz., DPC-23 (Early Mutant selection of DPC-9), IPC-30 and IPC-31 (Mutants of VP-I).
2. Seven new pistillate lines have been developed and stabilized Viz., DPC-22, IPC-41, IPC-42, IPC-43, IPC-44, IPC-45 and IPC-46 (derived from diverse parents through recombination breeding and pedigree method of selection). Among these, three pistillate lines viz., IPC-41, IPC-42 and IPC-44 were early flowering. DPC-22, IPC-44 and IPC-46 had 100-seed weight ≥ 33 grams.

Monoecious lines developed
Development of 46 diverse monoecious lines(ICS-396 to ICS-321 and ICS-406 to ICS 425) resistant to wilt 

Maintenance and multiplication of parental lines

• Maintenance of monoecious and pistillate parental lines of castor
• Production of nucleus, breeder, foundation and hybrid seed of castor varieties and hybrids through participatory method in farmers’ fields
