winter annual plant

The result showed that it s fit for planting in green house with characteristic of early mature, high yield and strong winterness.

经2年冬性鉴定试验表明,冬甘2号甘蓝是适合保护地栽培的春甘蓝品种,具有早熟、丰产、优质、冬性强等特性。

Three different winterness cultivars of winter wheat were used in the test of spraying period and dosage of SC2053.

用SC2 0 5 3在不同时期以不同剂量对 3个高产冬小麦品种进行化学杀雄 ,结果表明 :冬性不同的品种对SC2 0 5 3敏感性不同 ;主茎与大蘖处雌雄蕊原基分化～药隔分化期为SC2 0 5 3适宜的喷施时期 ;不同品种适宜喷施时期与剂量有差异 ,冬性较弱的济 92 4 14 2适于在雌雄蕊原基分化～药隔分化后期以 0 。

Overwintering ability and genetic variation of main agronomic traits were analyzed in different seasons.

【目的】分析特异水稻种质糯稻89-1越冬性及主要农艺性状的遗传变异。

The heritabilities of the overwintering ability of axillary buds were analyzed using four hybrid rice combinations, which derived from a new gramplasm resource of perennial waxy rice Nuodao 89-1 crossed with 4 different rice genotypes, and the genetic variation of main agronomic traits in F_2 generation was also investigated among the three combinations.

分析了源自多年生种质糯稻89-1和4个不同材料配制的杂交组合腋芽越冬性的遗传力和其中3个杂交组合F2代主要农艺性状的遗传变异。

Observation was made for two years on the overwintering ability of Dongxiang wild rice(Oryza rufipogon).

对东乡野生稻的越冬性能进行了连续２年的观察，结果表明：东乡野生稻的稻蔸能在武汉地区安全越冬，翌年春季再生苗从地表以下的茎节长出。
