海南花生种质资源农艺性状分析与评价

Analysis and evaluation of agronomic traits of peanut germplasm resources in Hainan

通过对海南17份具有地方代表性花生种质资源的试种试验,对其产量性状、农艺性状等进行分析和评价。结果表明:各种质间出苗率差异较大,生育期整体较短,植物学特性基本一致,饱果数、秕果数、产量差异较大,饱果数最多为16.5个/株,秕果数普遍较多,最多为13.5个/株,单产最高为3 520.95 kg/hm^2,出仁率普遍较高,最高的是wnxl1、为81.88%。相关性分析结果表明,产量与饱果数为极显著正相关。初试资源中wcql1、wcmh、wnhl、wnxl1产量表现突出,可进一步对其农艺性状及品质性状进行综合评价,从而为选育适应海南乃至热区种植的优良花生品种提供依据。

This paper planted local representatives of 17 germplasm resources in Hainan,their yield and agronomic characters were analyzed and evaluated. The results showed that there were large differences in seedling emergence rate among germplasm resources and all the growth period was short. It was broadly comparable to botanical characteristics consistent,full fruit number and blighted fruit number. But the yield of different varieties was significant. The most of full fruit number was 16.5 individuals/plant, and blighted pods were more generally,up to a maximum of 13.5 individuals/plant. The highest yield was 3520.95 kg/hm^2, kernel rate was generally higher, and wnxl1 was up to 81.88%. The correlation analysis showed that the correlation of yield and number of full fruit was significantly positive. In the initial resources,the yield of wcql1,wcmh,wnhl and wnxl1 performanced well, their agronomic traits and quality traits could be further analyze in order to provide basis for the selection of fine peanut varieties and adaption in Hainan and tropical areas.
