A bond of blood) is a 1962 Indian Telugu-language drama film directed by V. Madhusudhana Rao and produced by Sundarlal Nahata and Doondi.

A remake of A. Bhimsingh's Tamil-language film Pasamalar (1961), it narrates the story of bonding between Rajasekhar "Raju" and his sister Radha, who lose their parents at an early age.

The rest of the film focuses on the impact made by Anand's aunt Kanthamma on their lives post marriage.

Rakta Sambandham was released on 1 November 1962 and received positive reviews from the critics, who praised the performances of the cast, Ramana's screenplay and Madhusudhan Rao's direction in particular.

Due to a labor problem, the mill shut down, and Radha gave a depressed Raju one thousand rupees, which she had saved earlier.

Anand goes to meet Raju, but Malathi's brother Bhaskar expels him, who holds him responsible for his sister's plight.

Impressed with the commercial success of A. Bhimsingh's 1961 Tamil-language film Pasamalar (1961), Doondi and Sundarlal Nahata acquired its remake rights.

[2] Suryakantham, who played the role of an abusive mother-in-law, could not bear watching Savitri struggle and used to forget her lines.

With Nahata's encouragement, he composed new tunes for all the songs except "Chanduruni Minchu", "Bangaru Bomma Raaveme", "Manchi Roju Vastundi" which were retained from the original.

Venkat Rao, in his review for Andhra Jyothi dated 9 November 1962, stated that Ghantasala's music was instrumental in taking the film to the next level, and praised the lyrics for the songs "Manchi Roju Vastundi", "Bangaru Bomma Raaveme" and "Yevaro Nannu Kavvinchi".

[7] Radha Krishna, writing for Andhra Prabha on 11 November 1962, opined that Ghantasala's music was "uplifting" and praised the lyricists for their contribution.
