abstract

The ‘Plantain-Optim’ dataset (came from the ‘Plantain-Optim’ experiment conducted from 2009 to 2011 at CARBAP experimental station in Cameroon. The main objective was to describe agronomic potential of nine plantain varieties, including five natural plantains commonly cropped in Cameroon, and four plantain-like hybrids. A completely randomized bloc permitted to compare growth, development and yield of 45 plants per variety split between five replicates. Cropping practices guarantied non-limiting and homogenous conditions. Each plant was measured every 15 days. Data described aerial organ sizes, foliar structure and bunch characteristics of the mother plant. The ‘Plantain-Optim’ dataset includes the complete individual growth of each studied plantain of the ‘Plantain-Optim’ experiment with a 15-day accuracy. It is a useful standard of plantain varietal diversity for comparison with others datasets. Varietal growth and development homogeneity, biomass production or foliar and bunch structures could be further investigated. Moreover, these accurate data on plantain growth could be valuable for plantain 3D modelling.

2. Methods

2.1. Varietal panel definition

The first objective was to identify a panel of representative plantain varieties. To be studied a variety had to be either commonly cropped in Cameroon or promising with interesting characteristics as bunch structure or tolerance for a disease. A board of plantain researchers from CARBAP, compounded by four agronomists, one entomologist, two phytopathologists, two nematologists, one breeder, two socioeconomists and one post-harvest researcher, contributed to select the studied varieties. Each researcher choose among plantain varietal diversity ten interesting and promising varieties according to his own scientific expertise. All propositions were ranked to lead the final list of nine varieties, that included five natural plantains commonly cropped in Cameroon and four plantainlike hybrids (Table 1). We assumed that True horn type subgroup was excluded because of its small number of fingers per bunch. However, the nine selected varieties represent the three most cropped subgroups into plantain varietal diversity.
