Castor Research Station Junagadh Agricultural University Junagadh- 362 001 (Gujarat)
INTRODUCTION :
Castor belongs to the genus Ricinus, a member of the Euphorbiaceae, which contains a vast number of plants mostly native to the tropics. The genus Ricinus isconsidered to be monotypic and R. communis is the only species, which includes many polymorphic types. The cultivated types are dwarf annuals. Castor plants have well developedroot system with thick horizontal roots. Tap root looks like extension of the stembelow the soil. The stem is erect, circular in section, partially hollow, glabrous, and smooth with good branching. Stem is either red or green or with shades of both. The stem is markedby well-defined nodes from each of which a leaf is arises. The lower internodes are shorter and their length increases with height. Leaves are alternate, large, and palmate with 5-11lobes acuminate margins notched, serrate or indented. They are carried on long stoutpetioles. The inflorescence is borne terminally on the main and lateral branches. Flowersare large, in terminal sub panicled racemes, monoecious, apetalous, the upper portion ofthe raceme being occupied by the female flowers and the lower by male flowers The whole inflorescence may reach a length of 90 cm. The flowers are wind and insect pollinated and from 5 to 46 % natural pollination occurred. The fruit is round glaucous capsules with three projecting sides covered with tough spines or smooth, 3 loculed and three seeded. Seeds are albuminous, anatropous, broad, oval, compressed with a marked caruncle and longitudinal raphe. The testa is thin, brittle, varying in colour and mottling. Below the testa is thin legmen, covering a whitish oily endosperm containing the embryo. The Castor Research Station established at Junagadh of Gujarat state with the objectives to breed and develop high yielding, disease and pest resistant and better quality varieties of different oilseed crops like groundnut, castor, sesame, sunflower, soybean and mustard. Currently, the centre is actively engaged in groundnut and castor research works in the main areas like, • Plant Breeding& Genetics - Crop improvement • Agronomy- Crop production • Plant Protection: (a) Agril. Entomology, (b) Plant Pathology • Plant Physiology Junagadh Center has developed a world first Castor hybrid, GCH-3 (TSP-10R x J-1) during the year 1968.
RESEARCH IN CASTOR :
Mandates of research : 1. To evolve production technologies for newly developed and improved hybrid. 2. To screen and isolate diseases / pests resistant genotypes and incorporate the resistance in improved varieties. 3. To breed and develop genetically diverse male and female lines with good combining ability for yield and other agronomical attributes. 4. To disseminate information generated through research to farmers through front line demonstrations. 5. To develop varieties and hybrids of castor crop with high yield potential and early varieties and hybrids, better quality and disease and pest resistance. 6. To solve problems regarding castor production through radio, TV programmes, popular articles, hand outs, personal discussion, night discussion and by organizing farmers' day and week end training programmes etc. Objectives : 1. To develop agro technology and plant protection measures for newly released castor hybrid/variety. 2. To develop varieties and hybrids of castor crop with high yield potential, early maturity better quality and disease and pest resistance. 3. To develop male and female line of castor crop with high yield potential, early maturity, better quality and disease and pest resistance. 4.

EXTENSION ACTIVITIES :
FLD (Frontline Demonstrations) : The government of India, while realizing the import dependency of the edible oils, established the technology mission on Oilseeds (TMO) in 1986 which adopted four pronged strategy for reaping production, processing and storage technologies for attaining self reliance in oilseeds. The series of farmer oriented policies through TMO made an impact on the vegetable oil production of the country to shift from a stagnation stage to swift growth stage. The Adhoc Project on “Frontline demonstrations in oilseed Crops” sponsored by Department of Agriculture and Cooperation, Government of India was launched from Kharif, 1990-91. The above scheme amply provided opportunities to the researchers of the All India Coordinated Research Project on Oilseeds (AICORPO) actively in generation of location specific technologies for (1) demonstrating to farmers what they were advocating, (2) test their effect and viability, (3) obtain feed from the clients and (4) fine-tune the technologies to improve their acceptability and suitability to real farm situation.
