China Varieties Field Performance Report


By Dr. Qilong Duan ( Zoeve Seed Co., Ltd) Date: Oct 26, 2012
 

Rice is the staple food of more than half of the world‘s population. The production, processing and management of paddy rice have provided the basic conditions for the living of mankind. The production of rice has not only created employment opportunities for one billion agricultural populations in developing nations, but has also contributed to the development of the splendid culture associated with rice production. Hence, effective and productive rice systems play an influential role in development of economy and improvement of quality of life. In view of this, on 12th Oct, 2012, ZOEVE SEED CO., LTD dispatched a two person’s delegate (Dr. Qilong Duan, and Ms Cheery) visit IRAN, to investigate the performance of the varieties supplied by ZOEVE SEED CO., LTD, In order to highlight the china varieties performance, here we give a general report for this time field visit.
 
Visit date:  Oct 12th, 2012
Location: Shavoor Agriculture Research Station of Natural Recourse and Agriculture Research Center Khuzestan, Ahwaz, Iran



Trial Design
Spilt pot factorial design in randomized complete blocks with 3 factors (planting date, method, cultivar)
In order to get local farmer level or research habit level performance, we do not supply any guidance for special treatment for the varieties from china, so all the performance is base on the local cultivate traditional habit or local test standard.
 
Field Performance
1, growths condition
Plant growth vigor, plant height 75cm, each transplant field have a good tillers per hill, average length of panicle 24cm, flag leaf erect and narrow, high effective tillers, evenly panicle, 180-200gains per panicle, good uniformity, no disease, pest, logging, and weeds was good controlled, and no any other disappoint was found in trial field.



2, flowering and grain setting
Flowering condition is normal, the palea and lemma is open at good angle, anther is normal, pollen is strong, filament is long can enough stick out, the stigima is growth strong , hard and health pedicel , all the flower characteristic is good.






Seed setting
Re-milk and late milk stage, All the effective tiller have a good milk condition, no two stage milk phenomena found in trial field, milk stage is uniformity. The grain filled evenly and gradually, can guarantee a good quality after matured, the grain is slender and un-stick, seed setting is in good condition, about 87%



3, Yield expectation
According field trial designed cultivation and field growth condition, transplant density 90000hills/acre, 12 effective tillers/hill, 150 grains/panicle, 25g/1000grains(moisture 12.5%), the total theory yield would be 4050kg/arce, almost achieved the china level. Almost 35% higher yield than local OP varieties, a more yield can be expect if more factors were create to match this varieties.




Expert evaluation

Dr.Qilong Duan(china):  
These type china varieties have good adoption in Iran and all the growth condition is as good as in china, only plant height, panicle length a little change, other characteristic is remained almost the same as in china. Only irrigation limitation must be first taking into consideration. So we must select the right time to sowing, this type varieties can be cultivate in large rice plant area, and wish this varieties can do great contribution to Iran agriculture development and the farmer income.
 
Something needs improving, Cultivate manner must according local farmer habit to design the factor level, such as density, fertilizer, and irrigation condition etc. it will be very useful to accept by the farmer and get right varieties to serve for the farmer.



Dr. Majid Sattari(Iran):
China varieties growth is vigor, strong tiller capacity, bigger panicles, more grains per panicle and weightier panicle , and grain is bigger than local OP varieties, it shows good adoptability in our field, and the potential, we have done trial for selecting planting date, method, cultivar work, and will do more trial in different location in Iran to find the proper cultivate technology for china varieties, we hope, under the china scientist and technical support, we can great improve Iran agriculture using china germplasm in recent years, at the same time we will do some breeding research applying china germplasm and local germplasm, hope we can innovate some expecting varieties which suitable for Iran ecology and farmer cultivate habit.
 
Other expert: The other entire concerned experts endorse above evaluation and give their positive suggestion for next step.



Brilliant future
After field investigation,Ahwaz government concerned governor  and Khuzestan research organization and china expert sit together to discuss for the future development of china germplasm, both side express the opinion completely on field performance of the hybrid rice varieties, at the same time give positive suggestion for exist problem during trial field operation and develop hybrid rice in Iran.



Both side have confident, and have interest to continue the trial and introduce china varieties into Iran, ZOEVE will supply more seed to Iran to trial in main rice belt (along the Caspian Sea), more advanced technology will be supply by ZOEVE and some technical will be dispatched to Iran (if Iran needs) to guide the Iran farmer how to properly applying hybrid rice, at the same time, some Iran Canola will be introduced to south- north part of china. Bilateral party have confident and motivation to promote the hybrid rice development and will exchange any information on both party’s research improvement time to time.



Through bilateral government cooperation, the hybrid rice project can be enhanced in technology, finance and policy level. More and more china advanced germplasm and technology can be introduced to Iran, more policy can be made to promote the hybrid rice effective and fast application.



Hope most of the Iran farmers can skillfully using hybrid rice and greatly increase income in recent five years under both side efforts, Most of the rice cultivate area can be covered with hybrid rice. The total quantity of rice production can be increased 20% or more than present local OP varieties.
