Developing monoecious line of muskmelon (Cucumis melo L.)

Description

Muskmelon  (Cucumis  melo  L.)  is  an  important  cucurbitaceous  crop  grown  as  a  ‘Dessert  Crop’  throughout the  warmer  parts of world.  In the course of investigations  on  evaluation  and  characterization  of  muskmelon  genotypes  at  CIAH, Bikaner,  a  monoecious  land  race  was  identified  from  the  genetic  stock  collected  from  Sirohi  district  of Rajasthan and  designated  as  AHMM/BR-8.  The  monoecious  plants  were  self  pollinated  and  the  seeds  were  collected Separately.  The  individual  plant  progenies of selected plants were raised for generation advancement.  Single plant  selection  was  exercised  based  on  earliness,  fruit  size,  flesh  colour  and  TSS.  The  obtained  population  was 
also  tested  for  stability  and  observed  monoecious  sex  form  in  all  plants.  Plants  of  this  line  produced  round  fruits with  salmon  orange  coloured  flesh  of  3.2-4.0  cm  thickness,  10.8-11.3  TSS  and  478-570  g/cm2  hardness.  Plants start  to  produce  female  flowers  in  45-48  days  after  sowing.  The  number  of  fruits/  plant  was  found  to  be  3.47- 4.27  weighing  0.8-1.10  kg  which  develop  full  slip  at  ripening.  The  biochemical  analysis  was  also  done  for  total Sugar  (336.9  mg/g),  tannin  content  (0.12  mg/g),  phenol  content  (34.7  mg/g)  and  flavonoid  content  (1.05  mg/g) on  dry  weight  basis.  Thus,  the  presence  of  stable  monoecious  sex  form  in  this  line  could  be  utilized  in  F1  hybrid production  of  muskmelon.
