Бугунги кунда ер юзида содир бўлаётган глобал иқлим ўзгаришлари республикамиз ҳудудида етиштирилаётган қишлоқ хўжалиги экинлари ҳосилдорлиги ва сифатига ўз салбий таъсирини кўрсатмоқда. Айниқса, сўнгги йилларда об-ҳавонинг кескин ўзгариши, кетма-кет қурғоқчилик бўлиши, йиллик ёғин миқдорининг ўртача кўп йиллик ёғин миқдорига нисбатан анча кам бўлаётгани, баҳор ойлари охирида кузатилаётган кучли иссиқ ҳарорат лалмикор майдонлар шароитида етиштирилаётган кузги юмшоқ буғдой ўсиши ва ривожланиши, дон ҳосилдорлиги ва унинг сифатига жиддий зарар етказмоқда. Юқоридагиларни инобатга олиб, лалмикор майдонлар тупроқ иқлим шароитига мос бўлган, сувсизликка чидамли кузги юмшоқ буғдойнинг (Triticum aestivum L.) янги нав ва тизмаларини танлаш илмий тадқиқоти давомида 35 та нав ва тизмалар синовдан ўтказилди. Тадқиқот ўтказилган минтақанинг об-ҳаво шароитлари маълумотлари билан нав ва тизмалар хусусиятлари таққослаб баҳоланди. Тадқиқот давомида кузги юмшоқ буғдойнинг ривожланиш фазалари, биометрик кўрсаткичлари, ҳосилдорлик элементлари, дон сифат кўрсаткичлари, ўсув фазаларида баргдаги хлорофилл миқдори, нормаллаштирилган фарқ вегетация индекси (NDVI – Normalized Difference Vegetation Index) каби кўрсаткичлари баҳоланиб, қимматли хусусиятлари юқори бўлган тизмалар танлаб олинди.

На сегодняшний день глобальное изменение климата негативно влияет на урожайность и качество сельскохозяйственных культур, возделываемых в нашей республике. В частности, засушливая погода в последние годы, уменьшение осадков за год по сравнению со средним значением количества осадков за много лет, возникающая в конце весны сильная жаркая погода наносят серьезный ущерб росту, развитию, урожайности и качеству зерна озимой мягкой пшеницы, выращеваемых в богарных условиях природной среды. С учетом вышеизложенного были изучены 35 линий и сортов мягкой озимой пшеницы (Triticum aestivum L.), устойчивых к водному дефициту и адаптированных к почвенно-климатическим условиям богарных районов. В ходе исследования оценивались такие показатели, как фазы развития, биометрические показатели, параметры урожайности, показатели качества зерна, содержание хлорофилла в листьях (в фазе роста), вегетационный индекс (NDVI – Normalized Difference Vegetation Index). Был проведен сравнительной анализ признаков сортов и линий в погодных условиях среды.
Global climate change has had a negative impact on the yield and quality of agricultural crops cultivated in our republic. In particular, dry weather in recent years, a decrease in annual precipitation compared to the average amount of precipitation over many years, severe hot weather in late spring , have caused serious damage on the growth, development, and yield as well as on the grain quality of winter soft wheat grown in rain-fed environmental conditions. Taking into account the above information, we have studied 35 lines and varieties of soft winter wheat (Triticum aestivum L.), those resistant to water deficiency, and adapted to the soil and climatic conditions of rainfed areas. In course of the research, such indicators as development phases, biometric indicators, yield elements, grain quality indicators, content of chlorophyll in leaves (in the growth phase), vegetation index (NDVI – Normalized Difference Vegetation Index) have been measured; and a comparative analysis of the weather conditions of the environment with characteristics of relevant varieties and lines – made.
