中籼稻品种E164的选育及开发利用研究

用复交系谱法选育成中籼稻中熟品种E164.该品种参加两年(1987～1988) 省区试,平均亩产481.5公斤,比对照密阳23平均亩增产10.7%;一年(1989) 省生产试验,平均亩产402.4公斤,比对照密阳23增产8.6%.株形优良,茎秆健壮,耐肥抗倒,分蘖力较强,穗大粒多,米质优,1985年参加省优质米评比,居参评20个籼稻优质米之首,1987年参加中国水稻研究所63个区试籼稻品种米质测定,名列第三.三年(1987～1989) 人工接病虫鉴定,中抗白叶枯病,抗至中抗稻瘟病和白背飞虱,高抗至抗褐稻虱;田间检查,纹枯病轻.表现为优质、高产、多抗品种类型.目前省内外正在加速开发利用,

RESEARCH ON SELECTION AND UTILIZATION WITH EXPLOITATION OF A MIDDLE INDICA RICE CULTVARE ''''164''''

A middle indica rice cultivar'E~(164)'was bred by using the pedigreemethod with multi-cross. Its average yield per mu by the regional testof the province-level in two year (1987-1988) was 481.5kg, more than10.7% of that of the check cultivar'MiYang23', and by the productivetest of the province-level in one year(1989)was 420.4kg, more than 8.6%of that of MiYang23. It was characterized by good form, robust stem,tolerance to fertilizer & resistance to lodging, stronger tillering ability,big earhead and quality rice, on the appraisal of the province-level ofquality rice in 1985, it occupied first place in 20 indica quality rice a-ppraised. On the determination of rice quality to 63 indica rice culti-vars with regional test by the Chinese Rice Research Institute in 1987,it came in third. Acording to the identification of diseases & pests bythe artificial inoculation in three year(1987-1989), middle resistance toBacterial Leaf Blight, resistance until middle resistance to Rice Blast andWhite-Back Rice Planthopper, high resistance to Brown-Back Rice Planth-opper and slight banded Sclerotial Blight on field inspection was showedby it. E164 belong in a type of variety with good quality, high yield &multi-resistance, now it is speeding up the utilization with exploitationaround the province.
