Since 1996, the Rice Research Institute of Liaoning Province has laid stress on the genetic improvement of stigma exsertion rate of japonica male sterile lines. By introducing the genes of high stigma exsertion rate from indica into japonica, a group of japonica male sterile lines with high stigma exsertion rate have been successfully developed. Their stigma exsertion rate have been greatly increased from less than 30% to more than 80%, resulting in an increased outcrossing rate over 60% and a high seed production yield of 3.0~4.5 t/hm^2. Moreover, using these sterile lines, a group of new japonica hybrid rice combinations such as Liaoyou 5218 (Liao 5216A/C418), Liaoyou 1052 (Liao 105A/C52) have been developed and released to commercial production.

自1996年以来，辽宁省稻作研究所加强了粳稻不育系的柱头外露率遗传改良研究，通过导入籼稻的高柱头外露率基因，选育了一批高柱头外露率的粳型不育系，柱头外露率由原来的30%以下逐步提高到80%以上，异交结实率可达到60%以上，杂交制种产量可提高到3.0~4.5t/hm^2，并配组育成了辽优5218（辽5216A/C418）、辽优1052（辽105A/C52）等杂交粳稻新组合，在生产上得到了大面积推广应用。

Compared with the CK, MET in seed dressing with 75-150 g/hm^2 could increase the ears 24.88%-66.51%, promote the stigma length 2.64%-6.16%, improve the stigma exsertion rate 0.88%-4.57% and enhance the angle of grain husk 6.93%-14.35%, so did the outcrossing rate and seed production.

与对照相比，用75~150 g/hm^2多效唑拌种，能够使成穗数、株头外露率、雌蕊长度和颖壳张开角度分别增加24.88%~66.51%，0.88%~4.57%，2.64%~6.16%，6.93%~14.35%，从而提高异交结实率和制种产量。

Compared with no spurting GA3, spurting GA3 could promote the stigma length significantly, but reduce the stigma exsertion rate、the angle of grain husk、the outcrossing rate and seed production significantly or extremely significantly.

与未喷施赤霉素相比，喷施赤霉素后，雌蕊长度显著增加，柱头外露率、颖壳张开角度、异交结实率和制种产量均极显著降低。

By using a DH population derived from a rice indica/japonica cross, genetic analyses of floral characters, such as percentage of exserted stigmas, stigma length, stigma width, style length, anther length, anther width, spikelet length, spikelet width, length-width ratio of spikelet, and panicle exsertion degree, were conducted in the present study.
