Pearl millet (Pennisetum glaucum (L.) R.) is an important crop for rainfed production systems and can play a significant role as a feed source for ruminants owing to its high yield and drought tolerance. It is well-established that the maturity stage can influence the chemical composition as well as the nutritional value of crops traditionally used for silage production, although quantitative evidence that this occurs with pearl millet under rainfed conditions is lacking. The current research assessed the agronomic characteristics, ensilability, intake and digestibility of a Brazilian pearl millet cultivar (IPA BULK1-BF) harvested at four different growth stages. Forage was harvested at 35, 50, 65 and 80 days after sowing and ensiled under laboratory and farm conditions. Apparent digestibility of the silages was determined using 24 male lambs. The results showed that dry matter (DM) and panicle and stem proportions increased with the advancement maturity. The silage evaluations showed that DM, total and non-fibrous carbohydrates and lignin concentrations increased, while crude protein, ADF and in vitro DM digestibility decreased with the increase in plant maturity. Additionally, the fermentation characteristics were improved with the increasing maturity. The digestion study showed that intake of DM and N as well as digestibility of DM and fibre fractions decreased, while lignin intake increased. The results obtained for the production of dry and digestible DM, the ratio of plant fractions and fermentation parameters indicate the possibility of harvesting pearl millet forage after 50 days after sowing for silage production in the Brazilian semi-arid region.

ABSTRACT - The objective of this work was to identify the quantitative trait loci (QTLs) associated with grain yield in a rice segregant population (GYP). A population of 245 inbred recombinant rice lines from the 'Epagri 108' (Oryza sativa subsp. indica) x 'IRAT 122' (O. sativa subsp. japonica) cross was
evaluated at different locations and years and genotyped by single nucletide polymorphism (SNP) markers. A map of 1,592.8 cM was obtained from
9,831 SNPs, identifying 25 QTLs. The following nine SNPs showed stability between the different environments: M1.37719614 and M6.9563117 for GYP;
M4.29340056, M5.25588710, M7.29115624, and M12.4534450 for 100-grain weight (HGW); and M1.38398157, M4.28368337, and M7.25991230 for plant height (PH). Six SNPs were not present in the linkage blocks: M6.9563117 and M4.1077080 for GYP; M5.25588710 and M6.8886398 for HGW; and
M2.34471005 and M8.5955948 for PH. The M6.9563117 and M5.25588710 SNPs were considered environmentally stable and were not present in the
linkage blocks, showing their high potential for use in marker-assisted selection for grain yield in Brazilian rice breeding programs.
RESUMO - O objetivo deste trabalho foi identificar locos de características quantitativas (QTLs) associados à produtividade em uma população segregante de arroz (GYP). Uma população de 245 linhagens puras recombinantes de arroz, do cruzamento 'Epagri 108' (Oryza sativa subsp. indica) x 'IRAT 122' (O. sativa subsp. japonica), foi avaliada em diferentes locais e anos e genotipada por marcadores de polimorfismo de nucleotídeo único (SNPs). Obteve‑se um mapa de 1.592,8 cM a partir de 9.831 SNPs, tendo-se identificado 25 QTLs. Os seguintes nove SNPs apresentaram estabilidade entre os diferentes ambientes: M1.37719614 e M6.9563117 para GYP; M4.29340056, M5.25588710, M7.29115624 e M12.4534450 para peso de 100 grãos (HGW); e M1.38398157, M4.28368337 e M7.25991230 para altura de plantas.
