The magnitude of genetic expression and associations among traits are important for the prediction of response to selection in diverse environments and provide the basis for planning and evaluating breeding programs. In this regard, a cross classification mating design was used to produce hybrid ...
Multilocation evaluation trials (MET) constitute an important step in the evaluation of breeding lines, in order to assess their adaptation and stability patterns across environments, and to ensure optimal targeting of the lines. Seven Musa genotypes comprising five plantain hybrids, one cooking ...
The East African highland banana (Musa spp. AAA) is an economically important food crop. The crop is affected by a number of diseases and pests. Genetic improvement of the crop is hindered by very low seed set and poor seed germination. The objective of this study was to compare seed set, seed qu...
The triploid plantain landrace Obino l Ewai (Musa spp., AAB genome) has been crossed with a wild diploid banana (M. acuminata subsp. burmannica var. Calcutta 4 , AA genome) to generate full-sib diploid and tetraploid hybrids combining good agronomic performance and disease resistance. Microsatell...
Plantains have long been a traditional staple food in many countries in West and Central Africa WCA). Similarly, the highland banana has been and still is a major food crop in Eastern and Southern Africa (ESA). However, the black sigatoka leaf spot disease epidemic, which reached ESA in the late ...
Genetic enhancement of plantain (Musa spp. L., AAB group) has aimed at producing hybrids with high yield, short stature, early maturity, fast crop cycling, and disease resistance. Two tetraploid clones derived from the plantain landrace ‘Bobby Tannap’ (BT) and ‘Obino l’Ewai’ (OL) were crossed to ...
A field experiment was conducted on thirteen (13) Musa hybrids derived from 4n x 2n crosses, three (3) checks and two (2) plantain landraces to evaluate phenology, growth characteristics and yield performance in a humid agro ecological zone of Nigeria. Fifteen (15) phenotypic characters were sign...
We attempted to determine ploidy level in the gametophyte and the sporophyte of Musa using pollen and chloroplast characteristics, respectively. In the gametophyte, interploidy differences accounted for 63.8 % of the genetic variance for pollen diameter and 87.5% for pollen stainability, the rema...
