作者从1962年以来,结合杂交育种,对黄麻遗传规律进行一些研究。本文报道了1962—1965和1972—1974七年中对7个杂交组合的7个经济性状遗传力的研究结果。 (1) 利用亲本和杂种第一代估算环境变量的方法, 即h_B~2％=((V_(F_2)-1/3(Vp_1-Vp_2-V_(F_1))/(V_(F_2)))×100对黄麻七个经济性状的广义遗传力进行研究。不同性状的广义遗传力,从大到小依次为,分叉离地高度→生育期→皮骨比→茎高→鲜皮厚→茎粗→单株原麻重。其h_B~2n％的平均估值是:分叉离地高度60.73±15.30,生育期59.01±22.02,皮骨比58.14,茎高57.96±7.19,其遗传力较高;鲜皮厚41.30,茎粗31.40±14.50,单株原麻重29.26,其遗传力较低。不同性状在不同组合、不同年份的遗传力表现不同。
The author from 1962, combined with crossbreeding, genetic laws of jute some research. This paper reports the results of seven studies on heritability of seven economic traits in seven years from 1962 to 1965 and from 1972 to 1974. (1) The method of estimating environmental variables using the first generation of parents and hybrids, ie, h_B ~ 2% = (V_ (F_2) -1/3 (Vp_1-Vp_2- V_ (F_1)) / (V_ (F_2))) × 100 The general heritability of seven economic traits of jute was studied.The general heritability of different traits, in descending order, is the height of bifurcated off-ground → the growth period → the ratio of skull to bark → the height of stem → the thickness of fresh skin → stem Rough → the original hemp weight of the plant.The h_B ~ 2n% of the average valuation is: fork height 60.73 ± 15.30, growth period 59.01 ± 22.02, skull ratio 58.14, stem height 57.96 ± 7.19, higher heritability The heritability of different traits in different combinations and years was different for the fresh skin thickness of 41.30, the stem diameter of 31.40 ± 14.50 and the original plant weight of 29.26.
