The demand for soybeans [Glycine max (L.) Merr.] in Mexico requires the development of more productive varieties that contribute to decrease the imports of this oilseed, and the consequent leakage of foreign exchange. Therefore, the objective of the present work was to develop a soybean variety with a long period of pod formation and grain filling (R4-R7) and located near the month of September, in order to promote a yield superior to the control varieties. The Huasteca 600 soybean variety originated from the hybridization of H88-1880 x H88-3868, lines adapted to tropical environments (maturity group IX), which was carried out in 1994. It is temporary and is recommended for the south of Tamaulipas and warm humid and sub-humid regions of Mexico. It is medium to high, with good branching and determined growth habit; leaflets are medium ovoid and medium green, flowers are violet, seed is medium (100 seeds weigh 15.7 g), sub-spherical, yellow and brown hilum. Presents 48 days to R2, allowing him to develop the period from R4 to R7 in the time of greater probability of rains, an advantage that contributes to the achievement of greater yield. The oil and protein content is 20.6% and 36.9%, respectively. It has a good level of resistance to mowing and weeding, to defoliation pests and to the disease “frog eye”, it also tolerates “downy mildew”, “ammunition shot” and “anthracnose”. It has a yield potential of 2 988 kg ha-1, 25% more than the Huasteca 200 control variety.
