Estimating The Genetic Parameters For Vegetative And Flower Growth In Muskmelon (Cucumis Melo L.) And Spraying With The Amino Acid Of The Proline And Boron Cultivated In Dry Erea In The Al -Qosh Region

Abstract

The research was carried out in one of the private fields in Al-Qosh district, which is about 40 km north of the city of Mosul, which is located on lines of longitude and latitude in the UTM system (X = 329971 Y = 4066833) during growing season, spring 2022, for the period from 1/4/2022 to 15/8/2022 To estimate the genetic parameters of the vegetative and flowering growth of three varieties of muskmelon commonly cultivated in the region (Alqoshy , , Meloky, and Walaty) according to the semi-raised cultivation system, under levels of the amino acid proline at concentrations (0, 500 and 1000 mg L^-1) and spraying with boron at concentrations (0 , 50, 150 mg L^-1) and the source of boron was borax acid, the percentage of boron in it was 17%. Using RCBD design within split split plot with three replicates .The result was summarized as  the Alqoshy melon was superior in stem length than , and total leaf area , while the Walaty variety was superior innumber of branches /plant , and earliest in male flowers . Increasing Boron concentration gave a highest  value in most traits . Using amino acid at 500 and 1000 mlg l^-1 resulted best value for all traits under the study . The interaction between the variety  Alqoshy with 150 mlg l^-1   was superior in stem length , and with 50 mlg l^-1 was superior in dry matter in vegetative growth. While interaction between Walaty melon with concentration of boron gave a high value in total chlorophyll . The interaction between Alqoshy and 1000 mlg l^-1 from amino acid proline was superior in stem length , dry matter and is earliest in male flowers , and with 500 mlg l^-1  gave a heights number of perfect  flowers per plant . Walaty with 500 mlg l^-1 of proline  result a high number of branches per plant , and with 1000 mlg l-1 was superior in male and perfect flowers per palnt.
