(original code 5275) was approved in Sichuan in 1997. A cumulative promotion of 6.5 million mu.
(1) Variety source: it was crossbred by crop Institute of Sichuan Academy of Agricultural Sciences with [(Wanya 2x2874) x (Caucasus x2874)] x] Mianyang 19 in 1988 and selected in 1992.
(2) characteristics: the variety is spring, green seedlings, semi-erect, medium tillering ability, high panicle rate, plant height 80-90 cm, ear length 8-11 cm, oblong, long awn, red shell, spikelet number 2r-30 per spikelet, middle spikelet fruiting 3 Mueller 4 grains, grain number 38 anthracene 42 grains per spike, grain red skin, egg orchard shape, shallow grooves, half-horniness, 1000-grain weight 45-50 grams, easy to open and thresh. Quality determination: bulk weight 770.8 g / L, flour yield 70%, crude protein 15.02%, wet gluten 41. 1%. The resistance was identified by the Institute of Plant Protection of the Provincial Academy of Agricultural Sciences from 1993 to 1996 as medium to high resistance to stripe rust, medium and high susceptibility to powdery mildew and scab, and its resistance was better than that of the control 80Mel 8. The whole growth period was about 190 days, which was 1-2 days earlier than that of the control 80Murray 8.
(3) yield performance: the average yield per mu was 372.5 kg and 330kg in provincial regional test in 1995 and 1996. 1 kg, respectively, 6% higher than that of the control 80-8. 3% and 6.2%; 7.9% higher than Mianyang 26. In 1996, the average yield per mu at 5 points in the production test was 305.4 mu, 10.1% higher than that of 80-8.
(4) suitable planting area: suitable for planting in all parts of the province. The density should be controlled in the fields with good fertilizer and water conditions, and attention should be paid to the control of scab and powdery mildew.
