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。
According to the principle of crop heterosis, the male sterile line (MsG28) of flue-cured tobacco was used to formulate “Guangzun No.4” male sterility hybrid combination in 1987. After years of multi-point experiment and demonstration, it passed the national Approval of Crop Variety Approval Committee. The main chemical composition of the combination of harmony, aroma quality, aroma better than K326, alternative to K326 as the main smoke formula, the average yield 152.4kg / mu, 13.7% higher than the control, the average price of 4.58 yuan / kg , 12.5% more than the control, the output value of 698 yuan / mu, 27.97% higher than the control, the upper and middle tobacco rates 82.75%, 4.42 percentage points higher than the control, anti-mosaic, bacterial wilt , Climate spot disease, black shank ability than K326, G28, with high quality, stable yield, strong resistance, wide adaptability, easy baking and so on.
