The common bean breeding program coordinated by Embrapa Arroz e Feijão released 50 new cultivars from 1984 to 2010. The aim of the present study was to estimate genetic progress in terms of seed yield and other agronomic traits achieved by the black-type common bean breeding program in Brazil over the 22-year period from 1985 to 2006. Two types of field experiments were performed to assess genetic progress. In regard to experiments on lines, the three best breeding lines from each of 11 evaluation cycles constituted 33 treatments. These evaluations were made in 20 environments and served to estimate progress in seed yield and seed size because these were the criteria applied in selecting the elite lines. Cultivar evaluations included nine cultivars recommended by Embrapa during the period under investigation, and the evaluations were established in 21 environments. These evaluations served to estimate improvements in reaction to angular leaf spot, plant architecture and tolerance to lodging because cultivars usually exhibit superior phenotypes for such characteristics. Evaluations were performed from 2008 to 2010. Estimated improvement in seed yield was 25.2 kg ha−1 or 1.1 % per year. Improvements were also found in tolerance to lodging (1.7 % per year) and 100-seed weight (0.65 % per year). There was no significant progress for the plant architecture and resistance to angular leaf spot traits. © 2014, Springer Science+Business Media Dordrecht. Source

Nowadays, the Vitamin A deficiency (VAD) is still a public health concern, being one of the most important components of the high rate of morbidity and mortality among children in developing countries. There is a high prevalence of night blindness caused by deficiency of Vitamin A. Children and pregnant women are particularly affected. Many pumpkins (C. moschata) genotypes present a great variability of carotenoid content mainly the beta-carotene. The objective of this work is to evaluate the variability of beta-carotene among pumpkins genotypes. Twenty biofortified pumpkins cultivated at Embrapa Table Coastland and Semiarid were evaluated regarding beta-carotene contents.The analyses were carried out by High Performance Liquid Chromatography. The pumkinks showed a large variability in the contents of total carotenoids varying, in fresh pumpkins from 699.06 (genotype 25) to 124.60 g/g (genotype 26), from 106.96 (genotype 26) to 655.54 g/g (genotype 25) in samples cooked in boiling water and 117.55 (genotype 19) and 650.54 g/g (genotype 25) in steamed cooked, respectively.
