Flow Cytometry-assisted Screening of Gamma Irradiation-induced Nuclear DNA Content Variations in Cassava (Manihot esculenta Crantz) Genotypes

Dennis Obonyo, Miriam G. Kinyua, Kennedy C. Pkania & Emmy Chepkoech · Journal of Advances in Biology & Biotechnology · 2026

Gamma irradiation is a widely used physical mutagen in plant breeding capable of inducing a variety of DNA variations and chromosomal aberrations that manifest in the genome; therefore, flow cytometry (FCM), the gold-standard technique for estimating nuclear DNA content, provides...

Effect of Gamma Irradiation on Morphological Traits of Cassava (Manihot esculenta L. Crantz) Genotypes

Dennis Obonyo, Miriam G. Kinyua & Kennedy C. Pkania · Asian Plant Research Journal · 2025

Cassava (Manihot esculenta L. Crantz) is a perennial shrub characterized by outcrossing and a long breeding cycle, and significant inbreeding depression. Cultivated genotypes of cassava exhibit high heterozygosity; however, their reliance on vegetative propagation limits genetic...
