云南文山12个小麦品种（系）生产力水平分析

对12个小麦品种(系)的形态、经济性状、抗逆性和适应性进行分析,研究各品种(系)在云南省文山市的生产力水平,为品种审定和推广应用提供依据。结果表明：(1)有效分蘖数,有效穗数,穗粒数与千粒重是造成产量形成的原因,且穗粒数与千粒重是提高产量的重要因素；(2)参试的12个品种(系),仅有一个品种(系)蜀麦1619相对于对照品种(系)云麦56减产,其余均有不同程度的增产；(3)文D6-8植株整齐,长势良好,千粒重较高,籽粒大,饱满度较好,抗病性强,且产量最高,属于理想品系；(4)玉15-1株型紧凑,长势好,有效穗多,穗粒数较多,籽粒饱满,千粒重高,产量仅次于文D6-8；(5)易2011-1植株长势好,整齐度较好,穗大粒多,饱满度较好,千粒重较高,抗倒伏,产量居第三位。

Productivity Level of 12 Wheat Types (lines) In Wenshan,Yunnan

The morphological characteristics, economic traits, resistance and adaptability of 12 wheat varieties (strains) were analyzed to study the productivity level of each varieties (strains) in Wenshan City, Yunnan Province, to providing basis for variety identification and promotion. The results showed: (1) Effective tiller number, effective panicle number, number of grains per panicle and thousand grain weight were major yield component, and number of grains per panicle and thousand grain weight were important factors for increasing yield; (2) Among the 12 varieties tested, only Sumai 1619 was reduced compared with the control variety Yunmai 56, and yield of the other varieties increased; (3) Wen D6-8 was an ideal variety, with tidy plants, good growth, high thousand grain weight, large grain, good fullness, strong disease resistance and highest yield. (4) Yu 15-1 plants was compact and good in growth, with many valid grains, saturated grains and high thousand grains weight, its output ranked second.(5) Yi 2011-1 plants was good in growth with favorable uniformity, many grains, favorable saturation, high thousand grains weight and lodging-resistance, its output ranked third.
