ECOLOGIC VARIETY TESTING OF RICE OF FOREIGN BREEDING IN THE STRESS CONDITIONS OF KAZAKHSTAN PRE-ARALIE
Abstract
The rice-growing in Kazakhstan Pre-Aralie faces some problems because the region has a harsh continental climate and significant salty soils. However the varieties of local breeding with high productivity and great resistance to abiotic stressors are not resistant to biotic factors, which results in the decrease of their productive potential. In Kazakhstan rice productivity is on average from 4 to 5 t/ha and according to rice farmers it’s possible to increase its productivity due to introducing the new highly productive varieties and intensification of rice-growing. The ecologic trials of foreign, mostly Russian, varieties have been carrying out in Kazakhstan Pre-Aralie since 2010. 29 Russian varieties, 3 Uzbek varieties, 6 varieties of China, Italy and Turkey and 6 varieties of Kazakhstan have been tested. The standard variety is the local zoned variety ‘Marzhan’. The three-year results showed that the varieties ‘Lastochka’, ‘Tsaryn’, ‘VNIIR 10177’ and ‘Ivushka’ possessed the better yields and adaptive abilities to the local growing conditions of the Russian variety. These varieties are suggested and approved to use as an initial material for rice-breeding and they should be given to the State Variety Testing of MA RK to implement into production after its testing.
