Abstract
This study aimed to identify key morphological and biochemical traits influencing green forage yield in Cenchrus setigerus. The current investigation was carried out on 27 genotypes of Cenchrus setigerus fodder grass species at Grass Breeding Scheme, MPKV, Rahuri during 2021-2022. The study analyzed the suitable character selection for confirming indirect improvement of the yield. Indirect selection plays a crucial role in green feed improvement programs, as evidenced by the study's findings a highly significant positive relationship that green forage yield showed with dry matter yield per plant (0.945**), crude protein yield per plant (0.856**), leaf breadth (0.642**), plant height (0.454**), leaf length (0.454**) and number of leaves per plant (0.443**) at the phenotypic and genotypic levels. The characters dry matter yield (0.896**), leaf breadth (0.642**) and crude protein yield per plant (0.856**) showed high to moderate magnitudes of positive direct effects along with a highly significant correlation with green forage yield. This implies that choosing these traits will be very beneficial for raising the production of green fodder. The residual effect was 0.261, meaning that the features taken into consideration for the studies were responsible for around 74% of the variability.
