优质多抗粳稻品种垦育16号的特征特性及栽培技术

Characteristics and Cultivation Techniques of High Quality Multi-resistant Japonica Rice Variety Kenyu No.16

河北省农林科学院滨海农业研究所针对"高产、优质、多抗"的水稻新品种选育目标及亲本选配原则,以冀粳8号为母本、中花8号为父本杂交配组,以其F1代为母本,以关东100为父本进行复交,经人工接种抗稻瘟病鉴定、耐旱筛选、温室加代及大田多代定向选择,获得稳定水稻新品系垦育16号,2003年通过国家审定。该品种株高110 cm,结实率90%以上,千粒重约26 g,分蘖力中等,耐旱性强,不早衰,米质优异,综合抗病性强。国家水稻区域试验平均产量为8022 kg/hm2,较对照(中作93)增产8.8%。垦育16号在河北省唐山市生育期170 d,可采用旱育稀植栽培技术,秧田播种量为2 400～2 700 kg/hm2,插秧密度为30 cm×15 cm,4～5株/穴,缺水条件下可采用直播种植技术。

The new japonica rice variety Kenyu No. 16 with high yield, high quality and multi resistance was bred by the Institute of Coastal Agriculture, Hebei Academy of Agriculture and Forestry Sciences, which was approved in 2003. It had the characteristics of 110 cm of plant height, above 90% of seed setting rate, about 26 g of 1 000- grain weight, medium tillering ability, strong drought tolerance, without premature senescence, excellent grain quality, and strong comprehensive disease resistance. The average yield was 8 022 kg/hm2 in the national regional test, which increased by 8.8% than the control. It grew 170 days in Tangshan, the dry raising seedling and thin spacing transplanting techniques could be used with the seeding rate of 2 400 - 2 700 kg/hm2, transplanting density of 30 cm x 15 era, and 4 -5 plants per hole. The direct seeding technique could be used under water stress condition.
