摘要: 对国际水稻遗传评价圃(INGER)资源进行适应性试种、农艺性状观察、抗稻瘟病和耐贮藏性鉴定评价。结果表明:INGER资源的平均株高、穗长、剑叶长度、有效穗数和穗粒数均大于对照,平均千粒重、结实率均小于对照,INGER资源平均生育期偏长分别比两个对照品种优I66和威优77推迟了23 d和21 d;最后筛选出综合农艺性状优异的资源7份;通过对苗瘟、叶瘟和穗瘟抗性综合评价,筛选出高抗(HR)资源1份、抗(R)39份、中抗(MR)27份;经过42℃、RH88%人工老化21 d后,INGER水稻种质发芽率在60%以上的有126份,占85.71%,绝大多数表现为耐储藏、抗衰老性较强,筛选出9份发芽率在90%以上的耐贮藏材料。Abstract: Resource of rice germplasms in Fujian from the International Network for Genetic Evaluation of Rice (INGER) were evaluated for their ecological adaptability, agronomic traits, blast-resistance and storability. The results indicated that the mean plant height, panicle, flag leaf length, panicle count, and grains per spike of INGER were higher, but the average 1 000-grain weight and fertility were lower, than those of control. The growth period of INGER was 23 days longer than that of Youyi 66, and 21 days longer than that of Weiyou 77. Subsequently, 7 germplasms from the collection with excellent agronomic traits were subject to further evaluations on their resistances to the seedling-, leaf-, and neck-blast. As a result, one highly blast-resistant (HR), 39 blast-resistant (R), and 27 moderately blast-resistant (MR) varieties were selected from the INGER collection. After a 42℃, 88% RH artificial aging for 21 days, 126 INGER, accounting for 85.71% of the total, exhibited a greater than 60% germination rate. Most of them also showed desirable shelf life for storage and resistance to aging. In the end, 9 germplasms with more than 90% germination rate were identified.
