一、绵农3号绵农3号(8619-52)是绵阳农业高等专科学校小麦组用(75-21-4/76-19)F_4 作母本与(绵阳11号/Alondras)F_3代分离系作父本杂交,经五代培育选择育成的早播早熟小麦新品种。经绵阳、广元两市区试及生产试验,大面积示范栽培,于1993年4月通过省级审定,确定为推广品种。该品种全生育期为190—195天。株高90厘米,幼苗半直立,叶型微散,苗叶淡绿、长势旺,分蘖力较强、成穗率高,孕穗后叶色逐渐转深绿。穗层整齐,穗长12—13厘米,穗形方正、长芒白壳,穗大粒多,籽粒饱满、浅红皮,千粒重45—48克。落黄熟色好,易脱粒。高抗条锈病、白粉病,赤霉病轻,抗叶锈病性显著优于绵阳11号。含粗蛋白质13.18％,出粉率65.73％,容重 771.17克/升。
The results show that: (1) Mianong 3 Mianong 3 (8619-52) is the F_3 generation segregation (-75-21-4 / 76-19) F_4 and Mianyang 11 / Alondras wheat in Mianyang Agricultural College Department of parental hybrids, after five generations of breeding selection of bred early sown early maturing wheat varieties. The Mianyang, Guangyuan test and production test two cities, large-scale demonstration cultivation, in April 1993 passed the provincial-level validation, identified as the promotion of varieties. The variety of the whole growth period of 190-195 days. Plant height of 90 cm, semi-erect seedlings, leaves slightly scattered, light green leaves, flourishing, strong tillering ability, the ear became high, after the booting leaf gradually turn dark green. Ears layer neat, spike length 12-13 cm, spike Founder, long white shell, spike large grain, full grain, light red skin, grain weight 45-48 grams. Fall yellow color is good, easy threshing. Stripe rust resistance, powdery mildew, scab, light rust leaf resistance was significantly better than Mianyang 11. Containing crude protein 13.18%, the rate of flour was 65.73%, bulk density 771.17 g / liter.
