Genetic Variability For Yield And Other Agronomic Traits Of Groundnut(Arachis Hypogaea L.) As Induced By Sodium Azide

📄 Project Abstract

Groundnut improvement, through conventional method of breeding may not be able to create desired variability on which a robust breeding programme could be built. Also, groundnut as a self- pollinating crop naturally would have less variability in its gene pool. Thus, the present study was conducted (i) To determine the sensitivity of two groundnut genotypes to different treatment doses of Sodium azide (ii) To determine the effective treatment dose of Sodium azide for induction of variability among the genotypes, and, (iii) To evaluate variability for some agronomic traits modified by Sodium azide treatment. Two groundnut genotypes SAMNUT 22 and SAMNUT 24, obtained from IAR were treated with 10 mM, 20 mM,30 mM,40 mM, and 50 mM of Sodium azide concentration at the groundnut improvement lab for 6 and 12 hours. Each of the treated seeds and the controls were sown directly to well-prepared seed bed in the field to obtain the M1 plants. During the off season, a set of 10 seed each were picke...
