Comparatively little is known about the yield losses of corn leaf blightcaused by Helminthosporium maydis Nishikado and Miyake.Methods used inestimation of the losses of this disease in the past years wese only by grossestimations.This paper deals with quantitave relationship between yield andseverity of the southern leaf blight of corn.A field experiment was carriedout in Shun County of Honan province in the summer of 1977.A moderate sus-ceptible variety of Luo Yang white dent corn was used as experimental materal,and different levels of disease severity were established by using the fungicideof 50% wettable Dyrene sprayed at different infervals from 5 to 20 days.Theexperiment was carried out according to randomized bloks arrangment and 4replication were employed.The data obtained in this experiment was studied bycovaraince analysis.The relationship between yield of corn and severity of thisleaf blight was expressed by the multiple regression equation:(?)=28.26-0.1351X_1-0.1446X_2.Where(?)was the calcullated yield expressed as cattiesper plot,each plot equal to 0.032 mow,X_1 was the severity of disease at earlymilk stage of corn,that is at 30th August,and expressedas disease index in%,X_2 was the severity at late milk stage,which is at 15th September,Theequation of Yield Loss(%)=(?)X100 is suggested for use in disease lossassessment.

玉米小斑病(Helminthosporium maydis Nishikodo and Miyake)对玉米产量损失的影响,迄今所知甚少。1977年作者开始对此进行研究,采用中等感病品种洛阳白马牙,在自然发病条件下,间隔不同时期喷施敌菌灵保护叶面,人为地造成不同程度发病。结果表明,至流行终止期,各处理间有显著不同的病情差别,并相应地引致明显不同的产量差异。病情与产量呈极显著的负相关关系,进面推导出一个经验回归方程。(?)=28.26-0.1351x0.1446x2。经统计分析,此方程具有高度概括性,用试验中各组病情数值推算理论产量(?),误差均在允许的范围之内,说明本试验的经验方程具有相当高的精确度。

Relationships between yield components were analyzed in this paper with the data obtained from experiments under the subject of "Studies on High-Yielding-Rules and Measures in Spring Wheat" carried Out in Heilongjiang Province since 1975. The results showed that under the case of high-yielding level, as spikes per unit area reached a certain range (650-750 spikes/m~2 in the studies), the key of increasing yield continuously is to raise the productivity of spike and kernels per unit area. To increase kernels per unit area plays an important role in raising grain yield. The close relationships between kernels per unit area, kernel, weight/spike as well as 1000-grain weight and grain yield were found. There were also significant positive correlations between total spikelets, fertile spikelets and kernels per spike. According to the characteristics of both climate and. wheat development in the locality, it is necessary to develop cullivars with larger differentiated intensity of spikelet primodia, i. e. differentiating more spikelet primodia per unit time, and with more spikelets per spike on the one hand, and to increase the percentage of fertile spikelets per spike by means of increasing total spikelets per spike and their fertility with cultural practices on the other hand, and the latter is very important to the spring wheat of the locality. Regression analysis indicated that kernels per spike and 1000-grain weight were both closely correlated with kernel weight per spike, but T values in regard to the relationship between kernels per spike and kernel weight per spike were higher than that of between 1000-grain weight and kernel weight per spike regardless of genotypes and years as well as cultural practices used. The coefficients of variation of kernels per spike in different crop seasons, evironmental factors and cultivars were larger than that of 1000-grain weight. Also, the calculation of contribution of kernels per spike and 1000-grain weight to spike productivity increase showed that kernels per spike played a more important role than kernel weight. Therefore, in increasing kernel weight per spike, it is necessary to develop cultivars with characters of higher 1000-grain weight,highe intonsity of grain filling in both full and early filling period, and shortet grain filling duration.The rofe of cultural practices is mainly to ensure the realization of genetic potential of kernel weight.

文中指出,在高产水平条件下,单位面积穗数达到一定范围后继续增产的关键在于提高单穗生产力和单位面积粒数。单位面积粒数、穗粒重、千粒重与籽粒产量有密切关系。每穗总小穗数、结实小穗数和穗粒数之间也存在明显正相关。根据当地气候和小麦发育特点,一方面必需选育具有较大小穗分化强度和多小穗的品种,另一方面通过栽培措施增加总小穗数及其结实率以增加结实小穗数。穗粒数和千粒重均与穗粒重密切相关,但穗粒数与穗粒重之间关系的T值大于千粒重与穗粒重者。通过分析表明,穗粒数在提高穗粒重中作用大于千粒重。因此,必需选育具有千粒重高、整个灌浆期和灌浆前期灌浆强度大而过程短的品种。栽培措施的作用主要在于保证粒重遗传潛力的发挥。
