Abstract

Abstract:

Bindao 8(BD8),Bindao 10(BD10)and Bindao 18(BD18)are a series of new rice varieties with high yield and resistance,which were newly bred by Institute of Coastal Agriculture,Hebei Academy of Agriculture and Forestry Sciences,all showing the characteristics of bent ear large grain leaf under the rice.Under high-yield cultivation conditions,the yield exceeds 12.5 t/ha.This study used BD8,BD10 and BD18 as materials,compares them with their parents Jinyuan 89(JY89)and Kenyu 60(KY60),and the control variety Yanfeng 47(YF47),analyzes the yield composition,dry matter accumulation,and photosynthetic characteristics,and the mechanism underlying its high-yield.The results showed that the average yield of the Bindao varieties was 12.61-13.06 t/ha,which was 15.51% higher than that of YF47;the above-ground dry matter accumulation was 19.74-20.56 t/ha,which was significantly higher than the control by 16.45%;the yield reservoir capacity was increased by 14.5%-15.2% compared to the parents and the control;the thousand-grain weight was 28-30 g,which was 16.57% higher than that of YF47.After heading,the leaf area index of the Bindao varieties showed a trend of steady increase and slow decline,the photosynthetic potential was 356.83-378.58 (m²·d)/m²,which was 50.17% higher than that of YF47;the total chlorophyll content during the wax ripening period was high by 49.42%,and the net assimilation rate was 2.62-2.78 g/(m²·d),ensuring the material production during the later growth period.The apparent transfer rate of non-structural carbohydrates in the stem sheath was 39.26%-43.24%,and the efficient output during the early and mid-grain filling period could fill the reservoir capacity,with a grain setting rate exceeding 93%.In summary,the Bindao varieties achieve ultra-high yields through the synergistic effects of "large reservoir capacity+strong source supply smooth transportation",providing theoretical support for high-yield breeding of Japonica rice in North China.
