LAMZ-PIEDRA, Alexis et al. Preliminary evaluation of promising lines of common bean (Phaselus vulgaris L.) for early sowings in Melena del Sur. cultrop [online]. 2017, vol.38, n.4, pp.111-118. ISSN 0258-5936.

Common bean in Cuba is part of the basic food of population but their yields are not sufficient for self-supply due to the varied conditions in which this legume is grown and poor of cultivars adapted to these environments. This study was conducted in areas of the farm “Santovenia”, located in the municipality “Melena del Sur”. The objective of this work was to evaluate the agronomic performance of 15 lines of common bean, introduced in the collection of Local Agricultural Innovation Project (PIAL, according its acronyms in Spanish) that develops at the National Institute of Agricultural Sciences (INCA). Sowing was done in the first half of September 2013, in a randomized block design and including the commercial cultivar Cuba Cueto 25-9N (CC 25-9N) as reference. It was observed that genotypes in general study showed significant differences in the days to flowering, days to harvest maturity, number of pods per plant and yield. The plant height and number of grains per pods do not allow discriminating between the lines. All lines showed a shorter life cycle than the commercial variety, this allows escaping from drought. The comprehensive analysis of the results allowed proposing to the lines MH 43-2, MEN 2202-16, MER PRO 0334-126 and 2222-48 as the best performing of group, so they can be introduced into the productive practice
