Breeding Report on the Nationally Approved New Maize Variety,Longdan 336
摘要
Abstract
To promote the development of maize production in Gansu Province and meet practical needs,a new maize variety Longdan 336,which is high and stable yielding,high-quality,and disease-resistant,was successfully bred through germplasm innovation and superior gene aggregation.Longdan 336 is a hybrid developed using BSKKa570 as the female parent and BSKZ82 as the male parent.During 2014 to 2015,regional comparison experiment was conducted at 32 sites across Gansu in 2a,where Longdan 336 achieved an average yield of 10 080.0 kg/ha,8.8%higher than the control variety Demeiya 3,with a 100%yield increase site rate.In the 2020 production experiment of the northern early-maturing spring maize consortium,Longdan 336 recorded an average yield of 11 172.0 kg/ha,an increase of 349.5 kg/ha or 3.2%over the control.This variety has an average growth period of 125.9 days,plant height of 272.5 cm,ear height of 102.5 cm,ear length of 18.5 to 19.2 cm,15.0 to 18.0 kernel rows per ear,ear diameter of 4.8 to 5.2 cm,1 000-kernel weight of 372 g,and kernel rate of 84.3%.It is suitable for cultivation in early-maturing spring maize regions such as Heilongjiang,Gansu,Inner Mongolia,Ningxia,Jilin,Hebei,and Shanxi.关键词
