Inheritance and Stability of some Agronomic Traits of African Yam Bean (Sphenos‌tylis s‌tenocarpa (Hochst ex. A. Rich) Harms)

Inheritance and Stability of some Agronomic Traits of African Yam Bean (Sphenos‌tylis s‌tenocarpa (Hochst ex. A. Rich) Harms)

African yam bean (AYB), Sphenostylis stenocarpa, an indigenous African pulse has immense nutritional significance. The understanding of inheritance pattern and stability status of agronomic trait is primary to their genetic improvement. Thirty AYB genotypes were evaluated for 100 seed weight (100SW), seed weight per pod (SWP), days to 50% flowering (D50F) and days to seedling emergence (DSE) in a randomized complete block design of three replications. This study was conducted at Ibadan, Ikenne, Mokwa and Ubiaja in Nigeria. Genotypic variation was significant (p ≤ 0.05) for all characters except DSE. Location and Genotype x Location interactions were significant (p ≤ 0.05) for the four characters. D50F had the least genotypic and phenotypic coefficient of variation (GCV and PCV) of 10.26% and 11.05% , respectively. The highest GCV, PCV and genetic advance occurred in SWP at 34.55%, 37.88% and 64.94% , respectively. Broad sense heritability ranged between 77.61% (DSE) to 89.07% (100SW). Repeatability was highest (13.83%) in 100SW. The performance of TSs87, TSs91 and TSs125 was highly significant for DSE and 100SW. The joint regression analysis identified TSs24 and TSs82 as the most stable genotypes for DSE and SWP with regression coefficient (bi ) of 0.94 and 0.97 and deviation from linearity (Sdi 2 ) of 0.028 and -0.028 respectively. The most stable genotypes for D50F and 100SW were TSs61 and TSs84 with b = 1.015 and 1.017 respectively. The study revealed potential breeding values of four agronomic traits in AYB.
