“…The sugar content of plant sap in "Uzbekistan 18" was 17.4%, and it was 17.6% in sample 19, followed by sample 21 with 18.8% and sample 33 with 17.8%. The period from germination to paniculo process was very short, 60 days in the samples of the Botanical Research Institute (3,4,5,6,7,8,9,10,11,12,13,14,15), and it was 70 days in samples, 3, 4, 6, 12 and 15. It was observed that the duration of this period before flowering was much closer to the "Uzbekistan 18", and the period was shortened. This can be explained by an increase in temperature, and the active passage of the period from paniculo process to flowering.…”

“…Vakhopsky isolated hundreds of specimens. Throug using the method of selfpollination and selection, a number of varieties were created that exceeded the standards in terms of key characteristics that were valuable to the farm [1][2][3][4][5]10] Scientific research on the selection of corn for irrigated lands has also been conducted in the Central Asian republics [14]. In the 50-90s of the XX century, scientists of Uzbekistan S.K.…”

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.

“…At the same time, the speed of seed germination and root regrowth increases. Pre-sowing treatment of corn seeds with lowfrequency electromagnetic radiation increases germination energy and germination, promotes the formation of strong seedlings and increases the dry weight in seedlings [11,12]. Studies of the ozone-air mixture effect on corn seeds have shown a stimulating effect on the sowing qualities of seeds [13].…”

The aftereffect’s study of pre-sowing treatment with electric current of 500V, 1000V and 8000V on the sowing qualities and growth processes of corn hybrid seeds Rodnik 180 SV was carried out in laboratory conditions. As a result of the conducted studies, the positive effect of electrical stimulation on the germination and germination energy of corn seeds was revealed. Studies have shown the effectiveness of seeds’ pre-sowing electrical stimulation according to the following traits: growth of roots and seedlings, seed swelling intensity, germination energy and germination. Laboratory germination of seeds increased by 10% compared to the standard, germination energy – by 13-15%. The swelling intensity of treated seeds was 15-17% higher. The weight of raw sprouts in the control option was 32.3g, dry – 10.2 g. The weight of raw sprouts in seeds treated with 8000V was 48.9g, when treated with 500V – 54.0g. The length of roots and seedlings when treated with 8000V ranged from 23.9 mm, at 500V - up to 44.2 mm.

“…Успехи селекции определяются в основном генофондом самоопыленных линий, обладающих комплексом полезных хозяйственных признаков и свойств [1][2][3][4]. Эффективность семеноводства гибридов кукурузы определяется продуктивностью материнской формы и стабильностью ее проявления по годам в различных почвенно-климатических условиях, а также скороспелостью и уборочной влажностью зерна (для северных регионов), устойчивостью к полеганию и ломкости стебля после созревания (для южных регионов) [5,6]. Анализ метеорологических данных показывает, что для кукурузы формирование стрессовых условий явление нередкое.…”

В статье проанализированы двухлетние данные изучения элитных линий кукурузы по количеству дней от всходов до цветения початков, бесплодию, ломкости стебля растений ниже початка, пузырчатой головне, высоте растений и выделены лучшие генотипы с хорошей влагоотдачей при созревании и высокой урожайностью. Полевые опыты были заложены на опытных полях ВНИИ кукурузы в п. Пятигорский Предгорного района Ставропольского края. В изучении использовали 9 самоопыленных линий кукурузы. Сложившиеся погодные условия в разные периоды вегетации в годы исследования были относительно благоприятными для роста и развития растений. Комплексная оценка линий была проведена с применением селекционного индекса и индекса реальной урожайности. Селекционный индекс линий позволяет отбирать генотипы с оптимальным сочетанием высокой урожайности и уборочной влажности зерна. Индекс реальной урожайности напрямую зависит от устойчивости растений к ломкости стебля, что позволяет выделять генотипы, оптимально сочетающие высокую потенциальную урожайность, влажность зерна и устойчивость к ломкости стебля.
