Abstract

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.

- germplasm resources of rice,
- agronomic traits,
