BRS FC402: high-yielding common bean cultivar with carioca grain, resistance to anthracnose and fusarium wilt

Abstract

BRS FC402 is a common bean

BRS FP403: high-yielding black-seeded common bean cultivar with superior grain quality and moderate resistance to fusarium wilt

“…Grain yield was corrected to 13% moisture and measured in kg ha -1 . Sieve yield was determined in grain samples of 300 g per plot using sieves with oblong holes (4.25 mm width), according to Melo et al (2017). From the seeds retained in the sieve, a new 100 seed sample was taken to determine 100 seed weight.…”

“…In the final field trials, samples were taken from each plot with best results (highest mean yield and lowest coefficient of variation) to analyze cooking time and protein content. Analysis of cooking time were accomplished as described by Melo et al (2017), according to the TLPO Souza et al methodology adapted from Proctor and Watts (1987). The protein content was analyzed in bean meal (beans ground in a ball mill), according to the micro-Kjeldahl method.…”

“…Recommendations for regions and for growing season-specific cultivars have been a challenge, due to low use of certified seed. This low use of certified seed leads to low seed demand and, consequently, a low level of production, which has failed to generate a satisfactory income for the seed industry (Melo et al 2017). For that reason, a strategy commonly used for developing new common bean cultivars is to select superior elite genotypes with broad adaptation and yield stability (Pereira et al 2013, Melo et al 2017.…”

IAC Netuno: A new black bean cultivar resistant to anthracnose and Fusarium wilt

“…In general, the results of studies developed by research organizations in recent decades have led to an increase in total production and a decrease in growing area, which shows an expressive increase in yield beginning in the 1984/1985 crop season. A significant part of this result is attributable to some crop management factors, but plant breeding is the largest factor responsible for integrating genetic resistance to diseases and increasing the yield capacity of cultivars (Carbonell et al 2010, Barili et al 2015, Henrique et al 2015, Azevedo et al 2015, Melo et al 2017, Pelegrini et al 2017.…”

IAC Sintonia: new carioca common bean cultivar

“…However, plant breeding with the insertion of genetic resistance to diseases (Carbonell et al 2010, Henrique et al 2015, Azevedo et al 2015, Melo et al 2017 and an increase in the yield capacity of cultivars through various selection cycles have contributed to increase production potential, together with high quality of the grains. Barili et al (2015), reinforcing the importance of developing new cultivars, investigated the relationship between an increase in grain yield and the adaptability and phenotypic stability parameters in carioca (beige with brown stripe seed coat) bean cultivars recommended by several Brazilian institutions in the last 40 years, thus confirming that the effective increase in grain yield is the result of recommendation of new cultivars over the decades and that the cultivars recently recommended combine high yields, wide adaptability, and high predictability.…”
