Gene action for morpho-biochemical traits of sesame (Sesamum indicum) in different environments

Sesame (Sesamum indicum L.) is a drought tolerant oilseed crop with the highest oleic acid content, which isyet to be explored for its hybrid vigour. Therefore, present study was carried at Sri Karan Narendra AgricultureUniversity, Jobner, Jaipur, Rajasthan during 2019–20 and 2020–21 combining ability 11 seed yieldand attributing traits in 10 parents their 45 crosses sesame. The effects of general andspecific on morpo-biochemical attributes cultivars were studied utilizing half-diallel cross. Theexperiment conducted using randomized blocks design (RBD) 3 replications under different environmentalconditions. Significant variations detected among all recorded F1 generation also showed significant differences attributes. GCA (General Combining Ability)/SCA (Specialized Ability) variance ratio found less than one, indicating that non-additive gene action predominated tested RT–346, TKG–22, RT–372 RT–351 emerged as good combiners yield per plant environmental conditions. RT–346 × RT–351, TKG–22 RT–372, RT–103 specific cross combinations oil content. Incorporating hybrids high SCA into multiple crossings could beneficial strategy improving production content
