It is estimated that breeding contributed to around 20% of the yield growth between 1960 and 1980, and to 50% of the yield growthbetween 1980and2000(Evenson andGollin 2003;Qaim2016). It also deals with the topics including seed germination, environmental stress physiology, stomata function and dormancy. 1) selection of variety for mutation breeding, It should be the best variety available in crop and seed, should be pure.

US$ 199. Plant breeding can serve an important role in the success of sustainable farming because production requires seed or other propagules, regardless of management system. 941. indian council of agricultural research, krishi anusandhan bhavan ii, new delhi-11q o12. called plant breeding. The importance of hybridization in plant speciation and evolution has been debated for decades, with opposing views of hybridization as either a creative evolutionary force or evolutionary noise. Plant breeding started with sedentary agriculture and particularly the domestication of the first agricultural plants, a practice which is estimated to date back 9,000 to 11,000 years. For more than one hundred years, Plant Breeding and Genetics at Cornell University has been widely recognized for developing novel breeding methodologies and discovering economically important genes and varieties. 1.10.3 Plant Breeding. However, the role of plant breeding seems to have increased over time. Long spells of severe drought and serious out break of disease in some parts of the country led some futurologists to state that a possible doom in India by the end of the decade. New plant breeding technologies (NPBTs), including genetically modified and gene‐edited crops, offer large potentials for sustainable agricultural development and food security while addressing shortcomings of the Green Revolution.
