Classificação da incidência de área gessada do arroz de terras altas e o impacto das variáveis climáticas. 14
RODRIGUES, B.; BASSINELLO, P. Z.; BORBA, T. C. de O.; MATTA, D. H. da; STONE, L. F.; HEINEMANN, A. B..
O gessamento no grão de arroz torna-o opaco, mais quebradiço e com maior probabilidade de empapamento, portanto diminui a qualidade, além do valor de mercado. É um problema altamente influenciado por adversidades meteorológicas durante a safra. Até então, não há classificação oficial definida para a área gessada. Este estudo objetivou estabelecer uma classificação para a área gessada e determinar as variáveis climáticas que mais impactam esse defeito. Dados de quatro experimentos realizados em Porangatu, GO, e Vilhena, RO, safras 2018/2019 e 2019/2020, com 11 genótipos contrastantes, foram utilizados. A análise estatística foi dividida em três passos: 1) análise dos valores preditos da área gessada de 11 genótipos; 2) classificação dos valores preditos; e...

CNT96024-61-1-PSL-1-2-20-2 was a short-growth duration rice variety which was suitable for irrigated area encountered flooding in raining season. This rice variety derived from three–way cross of Suphanburi 1 /IR64//CNT86074-25-9-1. CNT96024-61-1-PSL-1-2-20-2 had maturity short growth duration so that it could be early harvested at about 87 days after sowing in wet season and 96 days in dry season. It had recorded yield potential of 1,004 kg/rai with the average yields of 681 kg/rai, which was comparable with the RD41 (742 kg/ rai), but 2% higher than that of RD43 (666 kg./rai). Plant stature of this variety was 80 cm. in height. Its grain was long slender shape, 10.54 mm. in length and 2.70 mm. in width, with straw colored paddy. Its 1,000 grains weight...

Pathum Thani 1 (PTT1) grown in Northern Thailand is often rejected by buyers on the basis of it poor quality, while it is a popular variety among farmers and rice mills in the Central region. This study evaluated head rice yield and chalkiness in dry season of PTT1 from different regions of Thailand. Samples of dry season 2011 crop of PTT1 were collected from the Upper North, Lower North, Central, East, and Northeast. Sixty-seven paddy samples were dehulled and milled individually. The milled rice of each sample was separated into head and broken rice to determine percentage of head rice. Percentage of chalkiness was determined by weight of chalky grain, in both whole and broken grain. The Central region had the highest percentage of chalkiness (49.1%) and...
