Abstract

Abstract:

To clarify the mechanism of yield and common characteristics of high-yielding cultivars of middle-season indica hybrid rice with different panicle sizes in the middle and lower reaches of the Yangtze River, the field experiments were conducted in 2019 and 2020 at Shucheng Agricultural Science Institute, Anhui province. 120 middle-season indica hybrid rice cultivars were classified into three panicle types by spikelets per panicle [large panicle size (LPS, 193-270), middle panicle size (MPS, 167-191), small panicle size (SPS, 108-166)], and their yield and yield components, growth period, daily yield, leaf area index, biomass, and panicle structure were compared. The results showed that rice yield varied across the cultivar types, irrespective of the panicle type. Cluster analysis revealed that it could be further divided into three yield types (high-yield, middle-yield, and low-yield). High daily yield was a common indicator of high yield among different panicle cultivars, LPS was associated with the increasing leaf area index, while MPS and SPS might be associated with the promoting light energy conversion efficiency. There were extremely different ways of producing high yields among panicle types, except daily yield. In yield components, the yield increasing of LPS mainly relied on the effective panicles, the spikelets per panicle, and 1000-grain weight; MPS was the effective panicle and the grain filling rate; and SPS was the effective panicle, the spikelets per panicle and the grain filling rate. This difference of panicle types was related to the classification method and the grain filling disorders of large panicle size rice. In terms of biomass, LPS and MPS cultivars were dependent on increased biomass to improve yield, but SPS high-yielding cultivars were dependent on the higher harvest index. There were no significant differences in the distribution of branches and panicle length among different yield types under each panicle type. Principal component analysis revealed that LPS high-yield cultivars were mainly characterized by higher daily yield, higher biomass, higher grain weight, more panicles, and higher leaf area index; MPS high-yield cultivars exhibited higher daily yield, more panicles, and higher biomass. However, SPS high-yield cultivars had higher daily yield, higher harvest index, more balance between panicle and spikelets, and higher grain filling rate. In general, the common indicators of LPS high-yield cultivars were daily yield 107.0 kg hm^-2 d^-1, biomass 20.2 t hm^-2, effective panicle 229.8 m^-2, leaf area index 6.1; MPS high-yield cultivars were daily yield 95.3 kg hm^-2 d^-1, effective panicle 253.9 m^-2, biomass 19.5 t hm^-2; and SPS high-yield cultivars were daily yield 79.6 kg hm^-2 d^-1, harvest index 61.0%, effective panicle 239.0 m^-2, grain filling rate 84.6%. In addition, high-yield nitrogen fertilizer management should be targeted according to the different panicle size cultivars.
