Research Project: EVALUATION OF PRODUCTIVITY OF CASTOR IN FIELD
2012 Annual Report


1a.Objectives (from AD-416):
The main objective of this cooperative research project is to evaluate productivity of castor selected for high oil content and yield. The research will lead to improved understanding of the environmental factors on oil accumulation and seed production. The research also includes tests of the productivity of dwarf castor cultivars.


1b.Approach (from AD-416):
Combined use of plant physiology and chemistry approaches has led to the identification of castor lines with high oil content and seed yield. These Lines will be assessed in field for seed yield per plant, seed weight, plant height, days to flower and days to maturity. Plants with high oil content and desirable yield traits will be selected for future breeding. Uniform, stable, high oil content and high yield castor cultivars will be determined by field performance.


3.Progress Report:

This project relates to parent project objective 1: Develop germplasm that enables domestic commercial production of natural rubber and ricinoleate by metabolic engineering and conventional breeding.

We have successfully performed the first field experiment on castor crop from June to December in 2011. About 400 reference plants and 400 testing plants were grown to maturity. Quantitative data from 2011 field testing have been collected. We are at the process of data analysis including seed oil content and yield. In June 2012 (the second year of the field testing), another sets of seeds were planted, with 400 for reference and 400 for testing plants. Quantitative data similar to that of 2011 will be collected and analyzed. The ADODR communicated project plans and reviewed the field research work and through frequent emails and telephone calls, and site visits from FY2011 to FY 2012.
