Component Compensation for Stability of Yield in Urad Bean at High Altitudes

Nineteen diverse and elite strains/cultivars of urad bean were studied at three locations of Himachal Pradesh representing middle and lower hill regions of the state to characterise the stability of yield and its components. JU 78-3 was the most stable variety with yield potential above the overall mean. High stability for pods/plant and seeds/pod conferred stability for yield on JU 78-3. All the five components varied in compensatory fashion to impart homeostasis to the filial and complex character of yield.
