Genetic variation of world soybean maturity date and geographic distribution of maturity groups
The maturity date of soybean (Glycine max (L.) Merr.) is sensitive to photoperiod, which varies with latitude and growing seasons. The maturity group (MG) system, composed of 13 MGs, is a major approach in characterizing varieties' ecological properties and adaptable areas. A total of 512 world soybean varieties, including 48 MG checks, were tested at a major site (Nanjing, 32.04°N) with portio...
متن کاملClassification of Multi - date , Tempo - Spectral data using NDVI values
NASA launched the Earth Observing System's flagship satellite "Terra," named for Earth, on December 18, 1999. Terra has been collecting data about Earth's changing climate Normalized Difference Vegetation Index (NDVI) is a simple graphical indicator that can be used to analyze remote sensing measurements. These indexes can be used to prediction of classes of Remote Sensing (RS) images. In this ...
متن کاملPlanting Date and Soybean Cultivar Maturity Group Affect Population Dynamics of Heterodera glycines, and All Affect Yield of Soybean.
Five soybean cultivars, one each from Maturity Groups (MG) III, IV, V, VI, and VII, all susceptible to Heterodera glycines, were planted in H. glycines-infested soil in April, May, June, and July at multiple locations in Arkansas and Missouri. The purpose of the study was to determine whether planting early reduces yield losses due to H. glycines. The population levels of cysts, eggs, and secon...
متن کاملPLANTÐINSECT INTERACTIONS Influence of Soybean Planting Date and Maturity Group on Stink Bug (Heteroptera: Pentatomidae) Populations
Field experiments were conducted in Stoneville, MS, to determine the impact of soybean planting date and maturity group on stink bug (Heteroptera: Pentatomidae) populations. Maturity group IV and V soybeans were planted on three planting dates in 2003 and 2004. Planting dateswere lateMarchÐearlyApril, lateAprilÐearlyMay, and lateMayÐearly June. Plotswere sampled weekly with a standard 38.1-cm-d...
متن کاملUsing near infrared spectroscopy to classify soybean oil according to expiration date.
A rapid and non-destructive methodology is proposed for the screening of edible vegetable oils according to conservation state expiration date employing near infrared (NIR) spectroscopy and chemometric tools. A total of fifty samples of soybean vegetable oil, of different brands andlots, were used in this study; these included thirty expired and twenty non-expired samples. The oil oxidation was...
