Understanding the nature and magnitude of variability existing among sweetpotato genetic materials for important traits is vital effective utilization such breeding purposes. Eighteen landraces from diverse origins, plus three released cultivars as checks, were evaluated in two contrasting locations, using nine agronomic eight morphological crop, to estimate materials, determine relationships traits, identify yield-related collections multivariate tools. The principal component analysis...
Sweet potato breeding in Africa, more especially Nigeria, has mainly focused on improving productivity farmers' fields and fresh root consumption. In order to target the program, study was conducted estimate magnitude of genotype × environment interaction (G E) select stable high yielding sweet genotypes for yield Cylas severity two locations, identify most discriminating representative test environments Nigeria. The 41 were evaluated across diverse using a randomized complete block design...
Aim: To investigate the performance of some improved sweet potato varieties obtained from National Root Crops Research Institute (NRCRI), Umudike, Nigeria, for root yield and other components. Study Design: Field experiment. Place Duration Study: Teaching Farm Federal University Agriculture, Makurdi in Benue State, located Southern Guinea Savanna Nigeria June-November 2010 2011. Materials Methods: The treatments comprised eleven [CIP 440141, K134, NASPOT4, NASPOT2, SPK004, TIS87/0087(check),...
The experiment was conducted in 2010 and 2011 to evaluate characterize fifteen in-country sweet potato accessions for root characteristics yield, plant habits, ground cover, severity of damage by Cylas puncticollis Meloidogyne incognita identify duplications. Significant differences (P<0.05) were observed number roots per plot, salable unsalable plot yield. highest tuber yield given E10, followed B21 while the lowest came from E17. result indicated B26 as highly susceptible C. puncticollis,...
Sweetpotato breeding in Nigeria and many other countries has largely focused on increasing productivity farmers' fields for fresh root consumption.In order to target the program processing end-use, variability, location performance, Genotype-by-Environment Interaction (GEI), heritability estimates relationships among important traits elite sweetpotato lines were studied two locations.The genotypes exhibited significant (p<0.05)genotypic variability at each dry matter, starch content, flour...
Understanding variability among elite Nsukka yellow spice pepper (Capsicum annuum L) breeding lines for nutritional and phenotypic traits is important if improvement programs are to deliver improved varieties nutrition. Much like traits, diversity exists most characters in pepper. Newly developed genotypes (Habanero) were evaluated morphological variability. Seed of planted under field conditions May 2017 2018. Data collected from mature fruit 8 qualitative 12 quantitative traits. There was...
The study was aimed at determining the in vitro nutritive value of mixed silages pennisetum purpureum and orange-fleshed sweet potato vines evaluating their potential being a new feed resource for ruminants during dry season. Pennisetum (Pp) (OFPV) were ensiled experimental silos bottles after wilting 24 hours following proportions viz:100%Pp (T1), 75%Pp +25%OFPV (T2), 50%Pp +50%OFPV (T3), 25% Pp +75% OFPV (T4) 100% (T5). Each treatment replicated ten (10) times kept 14 28 days laboratory...
