sterile spikelet

Genetic Analysis on Spike Length and Spikelet Number of Non 1B/ 1R and 1B/ 1R K Type Wheat Male Sterile Lines

非1B/1R和1B/1R类型小麦K型雄性不育系穗长和小穗数性状的遗传分析

The thousand-grain weight and the rate of sterile spikelet for varieties of weak springness wheat shewed very notable negative correlation.

弱春性小麦品种的千粒重和不孕小穗率呈极显著的负相关。

Meantime it can guard against the premature senility of later stage, reduce the numbers of sterile spikelet, enhance the numbers of gains per spike and thousand grain weight, increase the yield by 5% 26%.

同时防止后期早衰，减少不孕小穗数，提高每穗实粒数和千粒重，增产5%～26%。

Therefore booting water is needed for reduction of sterile spikelet and grout filling water for increase of grain weight.

建议及时灌孕穗水降低不孕小穗率，灌灌浆水提高小麦千粒重。
