The TAAR 349 MV corn hybrid is a trihybrid mid-season variety with a vegetation period of 116-119 days and FAO 290. Plants reach a height of 250-300 cm, are slightly bushy, and have an ear attachment height of 110-120 cm. The ear is cylindrical, 26-28 cm long, with 14-16 rows of kernels. Kernels are yellow, cream-colored and toothed, with a 1000-kernel weight ranging from 260 to 300 g, and a grain yield of approximately 80%. The hybrid exhibits high cold resistance, drought tolerance, and resistance to lodging, along with rapid early growth. It shows high resistance to diseases such as common rust and pests including corn borer. The energy potential of grain yield reaches 145 centners per hectare, while silage yield potential is 90-100 centners per hectare, making it versatile for various applications. The recommended plant population before harvest varies by region: 50-60 thousand per hectare in forest-steppe, 25-40 thousand per hectare in steppe, and 80-90 thousand per hectare in Polissia. These parameters ensure optimal development and maximum productivity of the hybrid under different climatic conditions.
