Estimates of Genetic Variability, Heritability and Genetic Advance for Blast Resistance Gene Introgressed Segregating Population in Rice
Rice is one of the most important stable cereal food crop in India. The total rice production was estimated at 103.61 million tones during 2015 16 (Government of India, Ministry of Agriculture) which is low as 1.87 million tones as compared to the year 2014 15 production (105.48 million tones) Rice blast is caused by fungal pathogen (Pyricularia grisea) which cause severe yield loss upto 50% world wide rice cultivable areas. (Scardaci et al. 1997; Shalini et al. 2016) Genetic variability is an important, where parental selection for hybridization (Chaudhary and Singh, 1982) and crop improvement primarily depends on genetic variability in base population (Adebisi et al. 2001) Segregating populations are essence for improvement of plant traits by adopting various breeding technologies for further improvement. Among all, F2 segregating generation has become more crucial and selection could be done meticulously.
