In desert conditions, corn is one of the most promising crops due to its resistance to salinity, drought, heat, adverse environmental conditions, high productivity and versatility. Conducting field experiments, sowing, phonological observations, biometric measurements, plant care, yield determination new varieties of agricultural crops were performed. Samples were also evaluated on the length of the paniculo. In particular, it was 44.7 cm in the control K–521, followed by 40.8 cm in K-431, 49.9 cm in K-581 and 55.4 cm in K-538, whereas in the technical variants, it was 55.4 cm in K-538, 50 cm at K-368, and even it was 65 cm in K-494. Of the 57 samples studied, only 8, № 9, 15, 17, 26, 27, 31, 42, 46 samples were found suitable for future selection work. Valuable aspects of these samples were that flowering period was 75-108 days, milk-ripening period was 87-108 days, and full ripening period was 118-130 days. These indicators were 76 days of germination, 79 days of flowering, 91 days of milk ripening and 127 days of full ripening in the “Orange-160” maize. It was found that the repining period of “Orange” maize was 9 days earlier than the control varieties, 9, 15 and 17.
