烤烟雄性不育系杂交一代组合“广遵四号”(904)选育

The Breeding of Male Sterile Hybrid “GuangZun No.4” (904)

根据农作物杂种优势的原理，利用烤烟雄性（胞质）不育系（ＭｓＧ２８），于１９８７年配制出“广遵四号”雄性不育杂交组合，经多年多点试验示范，１９９６年通过了全国农作物品种审定委员会的审定。该组合主要化学成分协调，香气质、香气量较Ｋ３２６好，可替代Ｋ３２６作主料烟配方，平均亩产１５２．４ｋｇ／亩，比对照提高１３．７％，均价４．５８元／ｋｇ，比对照增加１２．５％，产值６９８元／亩，比对照提高２７．９７％，上、中等烟率８２．７５％，比对照提高４．４２个百分点，抗花叶病、青枯病、气候性斑点病、黑胫病能力均比Ｋ３２６、Ｇ２８强，具优质、稳产、抗逆性强，适应性广，易烘烤等优点。

The new male sterile hybrid of tobacco“ GuangZun No.4”(904) was selected in 1987 by using the “MsG28” as female. The agronomical and industrial tests showed that its average yield, average price, output value and rate of high and middle grade cured leaf were all more than common cultivars. Its resistibility to tobacco mosaic, granville wilt, black shank, weather fleck were stronger as well as the fine quality, stable productibility, well adaptability and easy to cure.
