Self-incompatibility and seed set under different kinds of bagging methods for selfing in niger, Guizotia abyssinica Cass

摘要

India stands first in the production of niger in the world. From a mere 9324 tones valued at Rs. 21.36 crores, exports have gone up to 22,200 tones valued at Rs. 47.85 crores in 2001-2002. World trade in niger is about 50,000 tonnes and India is a major supplier to the world market. Besides, mainly used as bird feed, it is also a major ingredient in cattle feed mixture. It is cultivated as a minor oilseed crop in Madhya Pradesh, Orissa, Maharashtra, Bihar, Jharkhand, Karnataka and Andhra Pradesh andis extensively grown under rainfed conditions by marginal and submarginal tribal farmers. Though it has low productivity, production of seed depends on successful flowering, fruiting and seed setting. Thus, it becomes essential to gather information on the production of self seeds in considerable quantity, so that inbred can be developed for evolving new composite / hybrid. Therefore, the present study was conducted to know the self compatibility and the extent of seed sett in different types of bagging.
