41 Molecular Marker-assisted Selective Breeding of Sweet Pepper Inbred Line with Resistance Gene（L4）to Tobamovirus and Resistance Gene（Pvr4）to Potato virus Y
YU Hailong，WANG Lihao，ZHANG Baoxi，ZHANG Zhenghai，CAO Yacong Hot!
Tobamovirus is one of the most important viruses harming pepper production in China．In
recent years，damages by pepper mild mottle virus（PMMoV） has become more and more serious．The L
allelic genes（ L1，L2，L3，L4） are the main resistant genes providing resistance against Tobamovirus．In order
to improve the Tobamovirus and PVY resistance of pepper varieties，this experiment took‘ CM334’（ with
resistance to PVY，containing Pvr4 gene）and imported material ‘200375’（with resistantce to PMMoV，
containing L4 gene）as resistant resources，and sweet pepper inbred line‘ 83-163’（ medium resistance
to Phytophthora blight and CMV）as backcross parents，and conducted multi-generation backcross and
selfing．Utilizing molecular marker-assisted selection（MAS）combined with seedling resistance identification
and morphological selection，this experiment at last obtained the early-maturing，large fruit sweet pepper
selfing line ‘PT83-163’，polymerizing 2 resistance genes L4 and Pvr4，both resistant to Tobamovirus and
PVY（medium resistant to epidemic disease and CMV，containing resistant gene Pvr4 and L4）．By artificial
inoculation identification，line‘ PT83-163’ was resistance to disease and its horticultural traits were comparable
to that of the inbred line‘83-163’．

48 Effects of Exogenous 24-epibrassinolide on Tomato Seedling Growth and Potassium Accumulation Under Sub-low Temperature
YANG Lian，GAO Huan，WU Fengzhi
Taking 2 tomato varieties‘Dongnong 708’（‘DN 708’） sensitive to low temperature and
‘Dongnong 722’（‘DN 722’）tolerant to low temperature as test materials，this paper studied the effects
of 24-epibrassinolide（EBR）on tomato growth and potassium accumulation under sub-low temperature
condition．The results showed that comparing with the suitable temperature，low temperature stress could
inhibit the seedling growth of these 2 tomato varieties，and remarkably reduce the maximum photochemical
efficiency of PSII （Fv/Fm），and K+ concentrations in stems and leaves，and significantly increase the
malondialdehyde（MDA）content and electrolyte permeability．Moreover，the effects of sub-low temperature
stress on‘DN 708’was greater than that on‘DN 722’．While，exogenous EBR effectively alleviated
the inhibition of sub-low temperature stress on tomato seedling growth，significantly improved Fv/Fm，K+
concentrations in roots，stems and leaves of these 2 tomato varieties，and increased relative expression levels of
LKT1，SIHAK5 and SIHAK9 genes in roots and leaves，and significantly reduced MDA content and electrolyte
permeability in seedlings of these 2 tomato varieties．And the variation range in‘DN 708’was greater
than that in‘DN 722’．To sum up，exogenous EBR may increase the K+ concentration in various organs of
tomato seedlings by promoting the expression of transport related genes and K+ absorption，reduce the degree
of cell membrane peroxidation，and enhance the adaptability of tomato seedlings to sub-low temperatures
condition．Thus，exogenous EBR has a greater mitigation effect on low temperature sensitive tomato variety‘ DN
708’ under sub-low temperature stress than low temperature tolerant tomato variety‘ DN 722’．

56 Comprehensive Evaluation on Bolting Nature of Welsh Onion Germplasm Resources
YANG Guodong，LI Na，JIA Junxiang，TIAN Yun，JIANG Xintao，JIANG Binbin，CUI Lianwei
Taking 28 different types germplasm resources of welsh onion as research objects，this paper
selected 9 major traits at bolting and flowering stages of welsh onion as evaluation indexes on bolting nature，
and conducted comprehensive evaluation on welsh onion bolting nature by principal component clustering
analysis，average membership degree and bolting index methods．The results showed that the factors with
bigger contribution to principal component of welsh onion bolting nature were initial bolting date，early
flowering date，number of leaves and bolting speed．Their cumulative contribution rate reached 58.93%．
Specially，initial bolting date had higher correlation with the other indexes，which could be the leading
indicators for bolting nature evaluation．The bolting nature of different welsh onion germplasm resources could
be distinguished effectively by principal component clustering analysis，average membership degree and bolting
index methods．Among them，the average membership degree and bolting index methods could provide more
visual and clear partition on bolting nature of welsh onion germplasm resources．These 2 methods had similar
results．But the former’s merit was comprehensive，and the latter’s merit was simple and convenient．

62 Effect of Different Full Biodegradation Film on Stem Lettuce Production
LI Shuifeng,WANG Huaying，XU Chuchu，FAN Zhengwei，ZHONG Shuiliang，HU Meihua
Ten kinds of full biodegradation films with different specifications were introduced and tested
on stem lettuce production．Their effects on yield were studied．The results showed that except ‘Shanghai
black 6’，the other degradable films had no significant effect on stem lettuce yield comparing with the ordinary
polyethylene film．But there was the tendency of yield decreasing along with the decrease of film thickness．
The thinner the film thickness was，the faster the degradation rate was．The time duration for black degradation
film entering into induction period was generally earlier than that of the white one．Comprehensively seen from
film degradation status and stem lettuce yield，full biodegradation film‘ Yunnan white 10’ was the most suitable
film mulching for stem lettuce cultivation in early spring．

SHU Jun，HUANG Wenbin，LOU Jianying，FENG Guang，ZHANG Jianlong，LI Lebin，ZHANG Jingli，WU Xiaobao
Taking 3 types of pakchoi〔Brassica campestris L. ssp. chinensis（L.）Makino var. communis
Tsen et Lee〕with different bolting ability as test material，this experiment adopted different low temperature
and illumination to induce vernalization on seedlings，and studied the effects of 9 vernalization combinations
on vegetative mass，bolting，blooming and seed quality of pakchoi．The results showed that the maximum
differences in plant open width degree among different vernalization combinations in early，medium and late
bolting types were 17.1，6.3 and 6.5 times．And the maximum differences in single plant weight were 5.6，
2.8 and 2.9 times，respectively．The flowering date of each bolting type were significantly ahead of schedule，
along with the increase of vernalization days number．For the early bolting，medium bolting and late bolting
types，the maximum differences of flowering date between the different vernalization combinations of early
bolting and medium bolting types were 54，39 and 36 days．For the early bolting and medium bolting types，
the average single plant seed weight and germination rates were the best，when the vernalization treatments
were happened on 20-20，20-25，respectively．By adjusting bolting anthesis and seed collecting stage，
breeding generation-adding link and normal breeding cycle were complete articulation，thus realizing the
breeding target of 2 generations one year for pakchoi in southern Zhejiang areas．
