Maize Section, Department of Plant Breeding, Genetics, PAU, Ludhiana stated that the maize is the third most important food crop after rice and wheat in India. It is a versatile crop and can be grown under different agro-climatic conditions across the globe. Apart from staple food for human and quality feed for animals, it also serves as a basic raw material to thousands of industrial products. In Punjab, maize crop is grown in kharif as well as in spring season. Spring maize cultivation is an important cash crop for the farmers as it is highly profitable and commercially viable after harvesting of potato crop. The high water requirement of the crop can be rationalized by timely sowing, adopting bed sowing and drip irrigation practices. The following PAU improved production and protection technologies should be followed to rationalize its successful cultivation: Selection of varieties: The selection of suitable varieties is most important for economic returns of the crop. The single cross hybrids namely PMH 10, PMH 8, PMH 7, PMH 1 and DKC 9108 have been recommended by Punjab Agricultural University (PAU) for cultivation in spring season. PMH 10 : The plants of this single cross hybrid are medium tall with medium ear placement having broad leaves. Tassels are semi-open with green anthers. Silks are pink in colour. Ears are medium long, conico-cylindrical with attractive orange flint grains.
It matures in about 120 days. Its average yield is 31.5 quintals per acre. DKC 9108 : The plants are medium tall with low ear placement. It has broad and erect leaves with semi-open tassel. Anthers and silks are green. Grains are dull yellow, semi-dent with caps. It matures in about 122 days having average grain yield of 32.0 quintals per acre PMH 8 : This hybrid has medium tall plants with medium ear placement. The tassel is open with strongly curved branches anthers and silks are green. Pollen shedding and silk emergence are synchronous. It has medium sized ears with attractive yellow orange fl int grains with slight yellow capping. It matures in about 117 days. Its average yield is 31.0 quintals per acre. PMH 7 : This single cross hybrid has medium tall plants with curved and broad leaves. The tassel is open with strongly curved branches. Silks are green at emergence. Pollen shedding and silk emergence are synchronous. Ears are medium sized with orange flint grains. It matures in 115 days and its average yield is 30.0 quintals per acre. PMH 1 : It has tall plants with well developed root system. It has purple coloration in stem which is zig-zag and sturdy. Tassel is open and medium in size. Ears are medium long with yellow orange fl int grains. Its average yield is 27.6 quintals per acre and matures in 118 days. The farmers can produce hybrid seed at their own farm for these hybrids (except DKC 9108) following the guidelines of PAU. The technical guidance as well as seed of the parental lines is made available to the farmers of Punjab.
