Abstract:
The objective of the present investigation was to examine heterosis, heterobeltiosis, and inbreeding depression in ten bread wheat genotypes grown at the Research Farm of the Rajasthan Agricultural Research Institute, Durgapura, Jaipur, in Rabi 2021–2022. Significant differences observed in the mean performance of all the characters studied. For grain yield per plant and other yield attributing traits, the crosses Raj 3765 x UP 2425, Raj 4079 x PBW 343, Raj 4079 x Raj 3765, PBW 343 X HD 2967, Raj 4079 x WH 1021, Raj 4079 x HD 2967, HD 2967 x UP 2425, Raj 3765 x WH 1021 and Raj 3765 x PBW 343 exhibited significant and desirable heterobeltiosis over better parent. These crosses were recognized as desirable which may throw better transgressive segregants in succeeding generations. No inbreeding depression was recorded in any cross for grain yield per plant which can be used to maintain specific gene pool for future breeding programs of yield improvement in wheat.
