Abstract:
A study was conducted to examine variation in morphological characteristics in M2 plants of chilli (Capsicum annum L) variety Kashi Anmol (KA-2) at Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during Rabi 2017 (M₁ generation) and Rabi 2018 (M₂ Generation).The development of M1 generation was done by treating the seeds with five different dosses of gamma rays namely 10 KR, 20KR, 30KR, 40KR and 50KR and five concentrations of ethyl methane sulphonate (EMS), namely, 10mM, 20mM, 30mM, 40mM and 50mM were used individually as well as in five combinations of 10KR+20mM, 20wasKR+20mM, 30KR+20Mm, 40KR+20Mm, 50KR+20Mm along with control, without any treatment were used during the course of study. In the agricultural plot, the seedlings of the M1 generation were planted and the seeds obtained from them were harvested and transplanted for the analysis of morphological characteristics. The combination dose of gamma gay and EMS (10KR + 20mM) produced highest frequency (66.66) of viable mutations followed by 50KR+ 20mM (60.77). Maximum number of morphological mutants belonged to dwarf plant followed by early maturing plants, bushy plants hexamerons plants, narrow leaf, tall plants, high yielding plant. The viable mutants obtained for earliness, higher fresh fruit yield per plant, slender fruit and short plant height may be used in future breeding programmes.
